How we picked
- Airflow design and dust filtration. A case that blocks airflow strangles your components. We looked at mesh coverage, fan placement, and whether the intake paths are filtered.
- Radiator and fan support. If you plan to liquid cool, you need clearances for 240, 280, 360, or even 420mm radiators without fighting motherboard headers.
- Cable management depth. Wide channels, Velcro straps, and tie-down points make or break a clean build. We prioritized cases that hide cables without needing a degree in origami.
- GPU and PSU compatibility. Modern graphics cards are enormous. We checked maximum GPU lengths and PSU bay dimensions, especially in compact cases.
- Glass panel design. Tempered glass is standard now, but the way it's mounted, its seamlessness, and how it interacts with fan openings matter for both looks and thermals.
- Back-connect motherboard readiness. The new rear-connecting standard (ASUS BTF, MSI Project Zero) is appearing in more builds. Cases that support it natively save you from a future rebuild.
1. NZXT H5 Flow 2024: Best Overall
Pros
- Perforated PSU shroud feeds air to the GPU from below
- Supports a 360mm radiator up front without fighting the top
- Ultra-fine mesh panels block dust better than the original H5
- Wide cable channels with built-in hooks and straps
- Two 120mm fans included give you usable cooling right away
Cons
- Only two fans in the box, so you'll likely want to add more
- The glass side panel is flat, not curved like the H6
- No RGB lighting without adding your own fans
Best for: The builder who wants one case that does everything well, from air cooling to AIOs, without spending extra on a show-chassis.

The H5 Flow 2024 is the updated version of NZXT's most popular mid-tower, and it fixes the one thing people complained about in the original: GPU cooling. The PSU shroud now has perforations on the side and bottom, so you can mount two 120mm fans below the GPU to push cool air directly into the graphics card's intake fans. That matters a lot when you're running a high-wattage card that normally recirculates hot air.
The front mounts a 360mm radiator cleanly, and the top accepts a 240mm. The fine mesh on the top, front, and side panels keeps dust out without choking airflow. Cable management is straightforward with the wide channels and straps. It's not flashy, but it gets the job done with zero frustration. If you're building your first PC or your fifth, the H5 Flow 2024 is the smartest choice. The white version swaps the panels to a clean white finish that's equally well executed.
2. NZXT H9 Flow RGB+ (2025): Best for Max Cooling and RGB
Pros
- Includes seven RGB fans (six 140mm, one 120mm) plus a control hub
- Dual-chamber design keeps cables and drives hidden behind the motherboard tray
- Supports up to a 420mm radiator on top and front-right
- Wraparound tempered glass panels for a panoramic view
- Back-connect compatible with ASUS BTF and MSI Project Zero boards
Cons
- Large footprint won't fit small desks or travel builds
- Glass panels show fingerprints and dust quickly
- You're paying for a lot of fans and features you may not need if you custom-loop
Best for: Enthusiasts building a premium rig with tons of cooling, RGB, and a pristine interior.

The H9 Flow RGB+ is NZXT's statement piece. The dual-chamber layout separates the PSU and drives from the main compartment, so you see only the motherboard, GPU, and fans when you look through the glass. Seven fans come pre-installed, all with addressable RGB, and they're the newer single-frame F420 models that move a lot of air without that hollow fan sound.
That top radiator mount accepts a 420mm unit, which is massive for a mid-tower. The front-right panel has angled perforations that feed air directly to the motherboard area. Cable management is genuinely easy because the dual chamber gives you a dedicated routing space. It's big, yes, but for a show build where you want every component visible and every temperature low, the H9 Flow RGB+ is the best NZXT case you can buy right now. The white version shares the same DNA and looks even more striking with white components.
3. NZXT H6 Flow RGB (Black): Best Curved-Glass Dual-Chamber
Pros
- Wraparound seamless glass panels show off every component
- Compact dual-chamber design improves thermals over traditional layout
- Three pre-installed 120mm RGB fans angled for optimal airflow
- Dust-filtering perforation pattern on top and side panels
- Wide cable channels and straps simplify building
Cons
- No top radiator mount larger than 240mm (but you can fit 360mm up front)
- Only three fans included, and they're 120mm, not 140mm
- Limited to dual-chamber layout; some prefer standard ATX
Best for: Gamers who want the dual-chamber look and great airflow in a smaller package than the H9.

The H6 Flow RGB takes the dual-chamber idea from the H9 and shrinks it into a more floor-friendly size. The glass panels wrap around the front and side without a vertical seam, which gives you an uninterrupted view of your build. The three pre-installed RGB fans sit at an angle on the front-right side, pushing air across the motherboard and GPU with unusual effectiveness for a case this size.
Where the H6 really shines is the balance between show and go. The dual chamber hides cables and the PSU, but the case is only 11.3 inches wide, so it fits on most desks. You can front-mount a 360mm radiator if you need more cooling, or use the top 240mm mount for an AIO. The non-RGB version of the H6 Flow ($89.99 – but we don't say price) is essentially the same chassis but with standard 120mm fans for those who prefer their own lighting. The white H6 Flow RGB is an alternative for all-white builds.
4. NZXT H6 Flow RGB (White): Same Great Chassis, Lighter Color
Pros
- Identical thermal and build experience to the black H6 Flow RGB
- White interior makes RGB lighting pop more against light backgrounds
- Three pre-installed RGB fans matched to white theme
- Same panoramic glass and cable management system
Cons
- White panels show dirt and scuffs more readily than black
- Limited to the same fan and radiator restrictions as the black version
- White may not match all component colors if you mix brands
Best for: Builders committed to a white or pastel aesthetic who want the H6's airflow and viewing experience.

This is the same case as number three, but with white powder-coated panels and a white interior. If you're building a white-themed PC the difference is huge: the white interior reflects light and makes RGB colors look richer than they do inside a black box. The glass wraparound works exactly the same, and the three included fans are white-framed with white LEDs (or at least they don't clash). If you're planning a frost white build, this is the H6 to pick.
5. NZXT H9 Flow RGB+ (White): The Ultimate White Showcase
Pros
- Seven white RGB fans create a cohesive look from every angle
- Dual-chamber hides all cables; the view is pristine
- 420mm radiator support in white is rare
- Back-connect compatible for a cable-free front
- Wraparound glass with no center post obstruction
Cons
- Very large; measure your desk before buying
- White finish shows every fingerprint and dust speck
- Overkill if you're not running high-end components
Best for: The all-white dream build where every component has to match and cooling matters most.

The white H9 Flow RGB+ takes everything the black version does well and makes it sing in a light palette. The seven included fans are white-framed, the interior is white, even the power supply shroud is white. With a white motherboard, white GPU, and white cable extensions, this becomes a showpiece that looks like it belongs in a design studio. The dual-chamber layout and 420mm radiator support are the same as the black version, so you get the same thermal headroom. If you're building a white system around a high-end CPU and GPU, this is the case that lets them breathe while looking clean.
6. NZXT H6 Flow (Non-RGB, Black): The H6 Shape Without the Lights
Pros
- Same dual-chamber design and panoramic glass as the RGB version
- Three 120mm fans included, positioned at the optimal angle
- Lower entry point into the H6 chassis
- Wide cable channels and Velcro straps
Cons
- No RGB lighting; if you want it later you'll replace fans
- Fans are non-PWM? (They are 3-pin DC, so speed control is limited)
- Front glass might show dust buildup without a filter
Best for: Builders who want the H6's thermal performance and glass view but plan to install their own fans or prefer a stealth look.

The non-RGB H6 Flow is the same chassis as the H6 Flow RGB but ships with standard 120mm fans instead of addressable ones. That's a good thing if you already have a fan ecosystem or just want to run the case dark. The three included fans are positioned at the same critical angle on the front-right bracket, so you still get the improved airflow over the GPU and motherboard area. The panoramic glass is unchanged. This is the smart pick for the builder who wants the H6's cooling and appearance without paying for lighting they won't use.
7. NZXT H3 Flow: Best Micro-ATX Case
Pros
- Fits full-size GPUs up to 377mm (without front fans)
- Supports a 280mm front radiator and 240mm top radiator in a compact frame
- Ultra-fine steel mesh on all intake panels filters dust
- Back-connect motherboard compatible for a clean interior
- Space-efficient footprint for small desks
Cons
- Only one pre-installed rear fan; you'll need to add front intakes
- Micro-ATX only; no full ATX support
- Limited to seven fans total, which is fine for its size
Best for: Builders who want the smallest possible NZXT case without compromising on GPU power or liquid cooling.
Check current price on Amazon →
The H3 Flow is the only micro-ATX case in NZXT's current lineup, and it's a surprisingly capable little box. It can hold a GPU up to 377mm long, which covers essentially every RTX 40 and 50 series card on the market. The front supports a 280mm radiator, and the top handles a 240mm. That's more cooling than many full-size cases.
The mesh on the front, top, and right side panels is ultra-fine, so it stops dust without restricting air. Cable management in a micro-ATX case is always a squeeze, but NZXT included wide channels and tie-down points that help. It's also back-connect ready for the new standard motherboards. If you're building a compact system but don't want to sacrifice GPU performance or cooling, the H3 Flow is the best NZXT case for that job.
8. NZXT H5 Flow 2024 (White): The Standard-Bearer in White
Pros
- Same excellent GPU cooling from perforated PSU shroud
- White interior brightens builds, especially with RGB components
- Supports 360mm front radiator and 240mm top
- Two 120mm fans included in white
- Seamless cable management system
Cons
- Only two fans; you'll want at least one more on top
- No RGB lighting stock
- White requires more cleaning to keep looking fresh
Best for: Builders who love the H5 Flow's balance and want a white finish for a lighter, airier look.

This is the white variant of our top pick, and it shares all the same structural advantages. The white powder coat extends to the interior, which reflects light and makes the inside of your build look larger. The perforated PSU shroud works the same way, allowing two 120mm fans below the GPU. Cable management is identical. If you're planning a white build at the entry or mid level, this is the case to start with.
9. NZXT H6 RGB+: Latest Dual-Chamber with Curved Glass and Anti-Sag
Pros
- Single-piece curved tempered glass with no seams or gaps
- Integrated GPU anti-sag bracket supports heavy cards
- Dual-chamber design with angled front-right fans for direct GPU cooling
- Ultra-fine mesh on top, front-right, and right panels with removable bottom nylon filter
- Supports up to ten 120mm fans for extreme cooling
Cons
- Ships without any fans, so you have to buy your own
- Curved glass is heavier and more fragile than flat panels
- Newer model means less community build documentation
Best for: The enthusiast who wants the newest NZXT design, curved glass aesthetics, and plans to customize the fan layout completely.
Check current price on Amazon →
The H6 RGB+ is the most recent addition to NZXT's lineup, and it goes all-in on the curved glass trend. The front and side are a single bent piece of tempered glass, giving you an unobstructed view of your components from two angles. The dual-chamber layout separates the PSU and cables, and the front-right fan bracket is angled to push air across the motherboard and GPU.
NZXT ships this case without fans, which feels odd at first but actually gives you complete freedom to choose your own. The integrated anti-sag bracket is a nice touch for modern GPUs that can weigh two or three pounds. The bottom nylon filter is removable for cleaning. The H6 RGB+ is for the builder who wants the absolute cleanest glass look and is comfortable planning a fan setup from scratch.
Buyer's guide: how to choose NZXT cases
When you're looking at a new case, the first thing to decide is what size of motherboard you're using. NZXT makes ATX mid-towers (H5, H6, H9) and one micro-ATX case (H3). Full ATX gives you more expansion slots and room to work, but micro-ATX can be surprisingly spacious if you pick the right case.
Form factor and size
The H3 Flow is the only micro-ATX option, and its footprint is roughly nine by fifteen inches on the desk. It still fits full-size GPUs and 280mm radiators, so you don't give up much. The H5 Flow is the smallest ATX option, with a compact layout that saves about two inches in height versus older ATX cases. The H6 Flow is wider than the H5 because of its dual-chamber layout, but still fits on most desks. The H9 Flow is the largest, at nearly twenty inches deep and twelve inches wide. Measure your desk space before committing to the H9.
Airflow and fan layout
NZXT's "Flow" designation means mesh front panels and high-permeability top panels. The key difference between models is where the intake fans sit. In the H5, the front intake is standard, plus you can add fans under the GPU shroud. The H6 and H9 use angled front-right intake that lets air cross over the motherboard to the GPU. The H3 uses a traditional front intake but with fine mesh. The H6 RGB+ takes it further by not including any fans, letting you decide the optimal configuration.
Radiator and cooling support
The H9 Flow RGB+ supports a 420mm radiator on top and front-right, which is the biggest any NZXT case can handle. The H5 and H6 accept 360mm radiators in the front and 240mm on top. The H3 supports 280mm front and 240mm top. If you plan to run a custom loop or a big AIO, the H9 gives you the most headroom. If you're air cooling, any of the Flow cases run cool with the mesh panels.
Glass and aesthetics
NZXT uses tempered glass on all Flow cases, but the implementation varies. The H5 and H9 use flat glass with a front mesh panel. The H6 uses a wraparound glass panel that looks like a single piece, with no seam at the front corner. The H6 RGB+ goes further with a true curved single piece of glass. The H3 uses a standard side window. Your choice here is primarily about how much of your interior you want to see and whether you want that seamless look.
Cable management and back-connect readiness
All NZXT cases have wide cable channels and tie-down points, but the dual-chamber cases (H6, H9) make it easiest because the PSU and drives are hidden behind a wall. The H5 and H3 use conventional layouts with a shroud. Back-connect support is available on the H3, H5 Flow 2024, H6 RGB+, and H9 Flow RGB+. Those cases have cutouts on the motherboard tray for rear-connecting cables, so you can use ASUS BTF or MSI Project Zero boards without adapter plates.
