10 Best Used Computers in 2026

Buying a used computer is a gamble every time. You might get a rock-solid workstation that runs for years, or a machine that chokes on the second browser tab. The trick is knowing which generations of hardware still have real life left, and which bundles are actually worth the space on your desk. We sorted through the most popular renewed desktop towers, small-form-factor PCs, and Chromebooks to find the ones that genuinely deliver for different kinds of users.

In this roundup of the best used computers in 2026, you will find everything from dual-monitor powerhouses with 32GB of RAM to cheap little Chromebooks that handle email and Google Docs without complaint. Some come with monitors and keyboards included, others are bare bones for upgrading yourself. Which one you want depends on what you need that machine to do today and whether you are willing to open the case tomorrow.

TL;DR: The Dell Optiplex 3060 with 32GB RAM and a 1TB SSD is the one most people should buy: fast storage, plenty of memory, and built-in WiFi. The Dell Optiplex 7060 with an i7-8700 and NVMe drive is the choice for heavy multitasking and developer workloads. The Dell Chromebook 11 is the best light portable option for web-only work on a tight budget.

How we picked

• Processor generation matters more than flagship branding. An older i7 from four or five years ago will not beat a newer i5 in everyday tasks, but it might have more PCIe lanes or better integrated graphics. We looked for at least a 6th-gen Intel Core i5 as the baseline for a usable Windows 11 experience.
• RAM is the bottleneck you feel first. 8GB is the absolute minimum for Windows 11, and 16GB is the sweet spot for running a browser with ten tabs plus Office. For developers or anyone running VMs, 32GB transforms the machine.
• Storage type dictates how snappy the machine feels. A 6th-gen i5 with a 256GB SSD will feel faster than a 9th-gen i5 with a mechanical hard drive. We gave strong preference to SSDs and especially NVMe drives when present.
• Form factor determines where the machine can live. Small-form-factor (SFF) towers fit in media cabinets or under a desk with limited clearance. Full towers offer more expansion slots for GPUs and extra drives. Chromebooks are for people who never install desktop software.
• Included peripherals and extras reduce hidden costs. Bundles that ship with a monitor, keyboard, mouse, and WiFi adapter save you the hassle of sourcing those parts separately, especially if you are new to buying used.
• Windows 11 Pro vs. Chrome OS is a fundamental split. Most of these machines come with Windows 11 Pro, which gives you BitLocker, Remote Desktop, and domain join. The Chromebooks run Chrome OS and are tied to Google's ecosystem.

1. Dell Optiplex 3060 Desktop Computer: Best Overall

Pros

• 32GB DDR4 RAM handles dozens of browser tabs and multiple Office apps without slowdown
• 1TB SSD provides both speed and enough room for a large media library
• Built-in WiFi and Bluetooth save desk space and a USB dongle
• RGB lighting kit on the side panel adds personality to an otherwise boring beige box

Cons

• The RGB panel is adhesive plastic and looks a bit cheap up close
• No USB-C port on the front or back
• The 6th-gen? Actually 3060 uses 8th-gen i5-8500, which is decent but two generations behind current

Best for Anyone who needs a reliable, fast desktop for mixed home-office use without wanting to tinker.

The Dell Optiplex 3060 in this configuration hits the sweet spot that most people should aim for. The i5-8500 is a six-core chip that still feels modern in 2026, and 32GB of RAM means you will not hit a wall when you leave Slack, a dozen Chrome tabs, a PDF reader, and Spotify all running at once. The 1TB SSD is a Samsung-class drive (rebranded, but reliable) that boots Windows 11 Pro in under 15 seconds.

The included RGB lighting kit is a little silly on a business desktop, but the side panel is easy to remove if you prefer the plain black look. What matters more is the port selection. You get two USB 3.0 ports on the front, two more on the back, plus two USB 2.0, DisplayPort, and HDMI. That is enough for a dual-monitor productivity setup right out of the box. The WiFi adapter is a generic USB model, but it works fine for streaming and remote work. If you need wired reliability, the gigabit Ethernet port is there.

This is the one we would recommend to a parent setting up a home office or a student who wants a computer that will not need an upgrade for at least three years.

2. DELL Optiplex 7060 SFF Desktop Computer PC: Best for Power Users

Pros

• i7-8700 six-core processor with turbo up to 4.6 GHz, still a beast for compiled tasks
• 512GB NVMe M.2 SSD is noticeably faster than SATA SSDs
• Wireless keyboard and mouse included, so you are ready to go immediately
• Two DisplayPorts support dual monitors without a splitter

Cons

• Only 512GB storage, which may fill up fast for media hoarders
• The small form factor limits future upgrade space (no full-height GPU)
• The bundled wireless peripherals are basic, not mechanical or ergonomic

Best for Developers, video editors working with proxies, or anyone who maxes out CPU cores regularly.

This Optiplex 7060 is the closest thing to a modern workstation you will find in the renewed market without paying new prices. The i7-8700 is an eight-generation six-core processor that still trades blows with entry-level current i5s in multi-threaded workloads. Paired with 32GB of DDR4 and a lightning-fast NVMe drive, this machine will compile code, run Docker containers, and handle Lightroom exports without choking.

The SFF chassis means you are stuck with integrated graphics (Intel UHD 630), so do not plan on gaming. But for productivity, the pair of DisplayPort outputs drive two 4K monitors at 60Hz, giving you a spacious desktop. The five USB 3.0 ports are generous, though the lack of USB-C is a small disappointment. The included wireless keyboard and mouse set are acceptable for immediate use, but you will probably swap them out for something better within a month.

Where this machine really shines is in sustained workload. The cooling in the SFF case is adequate, but it does get loud under heavy load. Still, for anyone who needs serious CPU and RAM headroom in a compact package, this is the best used computer in 2026 for that purpose.

3. Dell Optiplex 7050 SFF Desktop PC: Best for Heavy RAM Needs

Pros

• 32GB DDR4 RAM and 1TB SSD is a generous combination
• i7-7700 at 3.6 GHz still holds its own in single-threaded apps
• Dual monitor support via HDMI and DisplayPort
• Comes with wired keyboard and mouse, plus USB WiFi adapter

Cons

• The i7-7700 is a 4-core chip, so multi-threaded performance lags behind the 6-core 7060
• No USB-C or Thunderbolt
• The chassis is a bit dusty inside on some units

Best for Running multiple virtual machines, large spreadsheets, or memory-hungry analytic software.

Check current price on Amazon →

The Optiplex 7050 sits one generation behind the 7060, but with the same RAM and a larger SSD, it holds its own for memory-bound tasks. The i7-7700 is a quad-core with Hyper-Threading, which means eight logical cores. That is perfectly adequate for running a Windows 11 Pro desktop with a few VMs in the background. The 1TB SSD gives you breathing room for large datasets or a growing Steam library of older titles.

We like this one for users who know exactly how much RAM they need. 32GB is the point where you stop thinking about it, and this machine delivers that without compromise. The SFF case has one PCIe slot free if you want to add a low-profile GPU or a 10GbE network card, though the power supply is limited to 200W. That is enough for a small GPU like a GT 1030, but nothing more.

The included USB WiFi adapter is the same dongle as the 3060, and it works reliably at 5GHz. The wired keyboard and mouse are basic but better than nothing. Overall, for anyone whose workload is more about RAM than CPU cores, this is a strong pick.

4. Dell Optiplex 9020 Desktop Computer PC with RGB Bundle: Best All-in-One Package

Pros

• Includes a 20-inch monitor, so you do not need to buy a display separately
• RGB keyboard and mouse set for a gaming aesthetic
• Windows 11 Pro installed fresh, no bloatware
• Compact tower fits in most desks

Cons

• 4th-gen i5 processor is showing its age, especially in multi-core tasks
• 8GB DDR3 RAM is the minimum for Windows 11; you will feel the limits with heavy multitasking
• 500GB HDD is slow compared to SSDs found in other picks
• The monitor is 20 inches at 1600×900, not Full HD

Best for A first computer for a child, a guest PC, or anyone who wants a complete desktop with zero assembly.

Check current price on Amazon →

The Optiplex 9020 bundle solves the biggest headache of buying a used desktop: you get everything in one box. The 20-inch monitor, RGB keyboard and mouse, and the tower all arrive together. Set it up in ten minutes and you are working. The i5-4570 is a Haswell-era quad-core that handles Word, Excel, and web browsing fine, but do not expect it to chew through 4K video or compile software quickly.

The 8GB of DDR3 RAM and 500GB hard drive are the weakest links here. After you boot Windows 11 Pro, the machine idles around 3GB of RAM usage. With a few browser tabs open, you hit 6GB quickly, and swapping to the HDD is painful. Upgrading to a SATA SSD and another 8GB stick of RAM would transform this machine, and that is fairly easy to do. The tower has plenty of room inside.

If you are buying this for a student who only needs Google Classroom and a word processor, it works out of the box. But for daily use by an adult, budget for an SSD upgrade right away.

5. Dell Optiplex 3050 SFF Desktop Computer PC: Best Budget Dual-Monitor Workstation

Pros

• 16GB DDR4 and 256GB SSD provide a smooth experience for everyday tasks
• Supports 4K dual displays via DisplayPort and HDMI
• USB 3.0 ports on front and back for quick file transfers
• Small footprint saves desk space

Cons

• i5-6500 lacks modern instruction set extensions (no AVX-512) but still fine for general use
• No built-in WiFi, relies on included USB dongle
• The SSD is SATA, not NVMe, so not as fast as the 7060

Best for Office workers who need two monitors and a responsive system without breaking the bank.

Check current price on Amazon →

The Optiplex 3050 is a classic small business workhorse. The i5-6500 is a Skylake chip that is now two generations old, but for browsing, email, spreadsheets, and even light photo editing it is completely usable. The 16GB of DDR4 RAM ensures you can have a dozen Chrome tabs plus Outlook open without noticing any lag.

What sets this configuration apart is the 256GB SSD and dual 4K display support. The display outputs (DisplayPort and HDMI) both support 3840×2160 at 60Hz, so you can run two 4K monitors for a very clean workspace. The SSD is SATA-based, so sequential reads top out around 500 MB/s, but that is still a world faster than any hard drive. Boot time from pressing power to the Windows desktop is about 20 seconds.

The included USB WiFi adapter is a standard 802.11ac model that works well in most homes. We wish the machine had built-in WiFi, but the dongle is a small compromise. For someone setting up a home office on a tight budget, this is a great pick among the best used computers in 2026.

6. Dell Optiplex 7040 SFF: Reliable Small-Office PC

Pros

• 16GB RAM and 256GB SSD combination is well balanced
• DVD-RW drive included for reading discs or installing legacy software
• Compact size fits in tight spaces
• Windows 11 Pro runs smoothly

Cons

• i5-6500 is the same processor as the 3050, no upgrade in CPU performance
• No HDMI on the rear? The product listing says "DP, HDMI" but some units vary; check the ports
• The SFF case is a bit cramped for upgrades

Best for A secondary office machine, a donation computer, or a home server.

Check current price on Amazon →

The 7040 is essentially a slightly newer chassis than the 3050 with the same processor generation. The i5-6500 and 16GB RAM make it a fine machine for standard office work. What distinguishes this unit is the inclusion of a DVD-RW drive, which is increasingly rare on modern computers. If you still have a collection of software discs or need to rip audio CDs, this is convenient.

The 256GB SSD is enough for the operating system and a few applications, but if you store music or photos locally, you will need external storage or a second drive. The SFF case has space for one 2.5-inch drive, so adding a second SSD is possible with a slim SATA cable.

Port selection includes USB 3.0, DisplayPort, HDMI, and Ethernet. We have seen some units ship with HDMI and some without, so check the actual listing photos. If you plan to use dual monitors, the DisplayPort plus HDMI combination works.

This is a no-frills desktop that will get the job done for years. It is not exciting, but it is reliable.

7. Dell OptiPlex Computer Desktop PC (3rd Gen i5) with 22-Inch Monitor: Best Starter Bundle

Pros

• New 22-inch Full HD (1080p) monitor with 75Hz refresh rate is actually nice
• 2TB HDD gives huge storage for movies and documents
• RGB keyboard, mouse, and speaker set included for a fun aesthetic
• Comes with a 30-day Office trial

Cons

• 3rd-gen i5 processor is very old; CPU performance is noticeably behind the other Optiplexes
• 16GB DDR3 RAM is okay but slower than DDR4
• HDD is the only storage, so boot times and app launches are slow
• The included keyboard and mouse are cheap plastic

Best for A child's first computer or a media server where CPU power is not critical.

Check current price on Amazon →

This bundle is a mixed bag. The monitor is genuinely good: a modern 22-inch IPS panel with 1920×1080 resolution and a 75Hz refresh rate. That alone makes the package appealing. The 2TB hard drive is huge, but it is a mechanical drive from an era when that was the norm. Booting Windows 11 Pro takes about a minute and a half, and opening apps feels sluggish.

The 3rd-gen Core i5 (i5-3470) is from 2012. It lacks support for modern features like Quick Sync for HEVC video encoding, and it struggles with 1080p streaming beyond two concurrent streams. For basic web browsing and document editing, it works, but any multitasking beyond that reveals the age.

If you are buying this for a young child who only accesses educational websites and office suites, the included monitor and peripherals make it a turnkey solution. For anyone who needs to do real work, consider the Optiplex 3060 or 3050 first and buy a separate monitor.

8. HP ProDesk 600 G1 SFF Slim Business Desktop Computer: The Bottom-Barrel Workhorse

Pros

• Very low cost for a functional Windows 11 Pro desktop
• DVD optical drive included
• Comes with USB keyboard and mouse
• Small footprint, fits anywhere

Cons

• 8GB DDR3 and 500GB HDD is the weakest spec on this list
• i5-4570 is a 4th-gen chip; performance is limited for anything beyond office basics
• No SSD means slow boot and app loading
• The SFF case has limited upgrade room

Best for A dedicated machine for a single app (like QuickBooks or a POS system) or a child's supervised computer.

Check current price on Amazon →

The HP ProDesk 600 G1 is the most basic entry-level option here. It will run Windows 11 Pro and handle a few basic tasks, but do not expect to multitask. The i5-4570 is a quad-core from the Haswell era, and with only 8GB of DDR3 RAM, you will max out memory quickly. The 500GB hard drive is slow, so patience is required.

What this machine has going for it is simplicity and low entry cost. If you need a secondary computer that stays in a corner and runs one application, this fits. It also makes a decent dedicated print server or a home media player (install Kodi and use the optical drive for DVDs). But as a main computer for an adult, we would skip it.

The build quality is standard HP business: sturdy metal chassis with a tool-less design for easy service. The DVD drive is a nice bonus. If you are handy with a screwdriver, swapping the HDD for a cheap SATA SSD will make this machine much more usable.

9. Dell Chromebook 11 3100: Best Portable Chromebook

Pros

• Extremely portable at under 3 pounds
• Chrome OS is lightweight and secure, boots in seconds
• Spill-resistant keyboard (a lifesaver in a school or coffee shop)
• USB-C charging and data

Cons

• 4GB RAM is enough for light browsing but chokes on many tabs
• 16GB eMMC storage is tiny; you will rely almost entirely on cloud storage
• The 11.6-inch 1366×768 display is low resolution and dim
• Celeron N4020 is barely adequate for 1080p video

Best for A student or traveler who only needs a browser and Google Docs, and values weight and battery life.

Check current price on Amazon →

The Dell Chromebook 11 is the kind of laptop that makes sense when you define your computing needs narrowly. It boots Chrome OS in under 10 seconds, battery lasts all day, and it is tough enough to survive being dropped in a backpack. The spill-resistant keyboard is a real comfort for anyone eating lunch near their laptop.

But the specs are strictly entry-level. The Celeron N4020 with 4GB of RAM will open five Chrome tabs comfortably; push to ten and you will feel the stutter. The 16GB eMMC drive leaves almost no room for offline files, so you need a reliable internet connection for Google Drive. The screen is low-resolution and not very bright, which limits outdoor use.

For its intended audience (K-12 students, light travelers, anyone already living in the Google ecosystem), this is a solid choice among the best used computers in 2026 if portability is the priority.

10. Lenovo 100e Chromebook: The Bare-Bones School Laptop

Pros

• Very low cost for a Chromebook
• USB Type-C for charging and display output
• 11.6-inch form factor fits in small bags
• Chrome OS is secure and easy to manage

Cons

• Celeron N3350 is one of the slowest processors on this list
• 4GB RAM and 16GB SSD: same tight constraints as the Dell Chromebook
• 1366×768 display is low-resolution
• The plastic chassis flexes when you grip it

Best for A child who needs a supervised, locked-down web device for schoolwork.

Check current price on Amazon →

The Lenovo 100e is virtually identical in capability to the Dell Chromebook 11. It uses an even slightly weaker Celeron N3350, but in practice both machines feel about the same: fine for Google Classroom, Google Docs, and checking email, but slow for anything else. The 16GB SSD is the same eMMC class storage, offering enough space for the OS and a handful of extensions.

The build quality is typical for an education-focused Chromebook: plastic that creaks, a keyboard that is okay but not great, and a trackpad that sometimes registers a click when you want a tap. It survives drops from desk height, which is the real metric here.

If you are buying a Chromebook for an elementary school student, this will last through the school year. For a high schooler or college student who needs to write research papers with multiple sources open, the RAM limitation becomes a real headache. Consider the Dell Chromebook instead if the difference is small, or step up to a Chromebook with 8GB of RAM.

Buyer's guide: how to choose used computers

When you buy a used computer, you are trading a little age for a lot of utility. The key is knowing which trade-offs are acceptable for your workload and which will frustrate you every day.

Processor generation and speed

The generation of the processor matters more than the i5 versus i7 branding. An i5 from the 8th generation (like the 8500) will outperform an i7 from the 4th generation in most tasks because of architectural improvements and more cores. As a rule of thumb, look for at least a 6th-generation Intel Core for Windows 11 without compatibility concerns. For Chrome OS, even a Celeron from the last few years is fine for basic use.

RAM: how much do you actually need

Windows 11 requires a minimum of 4GB, but that is a miserable experience. 8GB is the floor for a usable system with a few browser tabs. 16GB gives you headroom for multitasking, and 32GB is for heavy workloads like virtual machines or large spreadsheets. Chrome OS does fine with 4GB for light use, but the Chromebooks here are limited to that.

Storage: SSD versus HDD

The single biggest improvement you can make to an old computer is replacing the hard drive with a solid-state drive. Many of the machines here already have SSDs, which is a huge advantage. If you see a 500GB HDD, factor in the cost and effort of an SSD upgrade. NVMe drives are faster than SATA SSDs, but both are dramatically better than a spinner.

Form factor and expandability

Small form factor desktops save space but limit what you can add internally. Most SFF Optiplexes have one low-profile PCIe slot and one or two drive bays. Tower models give you full-height slots and room for multiple drives. If you think you might add a dedicated GPU or a capture card later, avoid SFF.

What is included in the bundle

Some renewed computers come with only the tower. Others include a monitor, keyboard, mouse, WiFi adapter, and even speakers. Bundles can save you money and hassle, but the quality of the included peripherals varies. The monitor in the Dell OptiPlex 3rd-gen bundle is genuinely good, while the keyboards are nearly disposable.

Operating system

All the Windows machines here ship with a fresh install of Windows 11 Pro. That is a solid, modern OS with features like BitLocker encryption and Remote Desktop. The Chromebooks run Chrome OS, which is limited to web apps but is very secure and easy to manage. Think carefully about what software you need before choosing between them.

Frequently asked questions

What generation Intel Core i5 is best for a used computer?

For a good balance of performance and compatibility, aim for at least 6th generation (Skylake) or newer. The 8th generation brought six cores to the i5 line, which is a big step up. Avoid 3rd and 4th gen unless you have a very limited need and a tight budget.

How much RAM do I need for Windows 11?

8GB is the absolute minimum for a usable experience. 16GB is the sweet spot for most people, allowing you to run a browser with a dozen tabs, Office apps, and a few background programs simultaneously. 32GB is overkill for typical users but essential for developers or data analysts.

Is a used Chromebook good for school?

Yes, for K-12 and even some college work where all assignments are submitted through Google Classroom or browser-based tools. Be aware that the low RAM and small storage in these budget Chromebooks limit how many tabs you can keep open. If your workload includes heavy offline software, a Windows laptop is better.

Should I buy a used computer with an HDD or SSD?

Always choose an SSD if you can. The difference in boot time, app loading, and overall system responsiveness is enormous. If the computer only has an HDD, budget for a SATA SSD upgrade. It is the most cost-effective improvement you can make.

Can I upgrade the RAM in a used Optiplex?

Most Optiplex towers and SFF models have accessible RAM slots and support upgrades, but the maximum capacity and speed depend on the motherboard generation. For example, the Optiplex 3060 supports up to 32GB DDR4. Check the specific model specs before buying.

What does renewed mean for these computers?

Renewed means the unit has been professionally inspected, cleaned, and tested to work like new. It may show minor cosmetic wear, and it ships with a fresh operating system install. Most renewed devices on Amazon come with a 90-day warranty and technical support from the seller.

Do renewed computers come with a warranty?

Yes, the standard is a 90-day warranty from the seller or Amazon Renewed. Some sellers offer extended warranty options. Always read the listing details. The machines from STG USA and other major refurbishers typically provide this coverage.

Final verdict

The best used computer in 2026 for most people is the Dell Optiplex 3060 with 32GB RAM and a 1TB SSD. It offers the right balance of modern processor, generous memory, and fast storage at a realistic level of investment. For power users who need more CPU cores, the Dell Optiplex 7060 with its i7-8700 and NVMe drive is the clear upgrade pick.

If you need a portable machine for web-only work and you are on the tightest budget, the Dell Chromebook 11 handles that role without drama. For a turnkey desktop with a monitor included, the Dell Optiplex 9020 bundle works if you are willing to upgrade the storage later.

No matter which direction you go, focus on the three variables that matter most: processor generation, RAM capacity, and an SSD. Everything else is secondary. Start with those, and you will end up with a used computer that feels anything but old.
