Best NZXT PC Cases: H5 Flow and H6 Flow Picks for 2026

If you are shopping for the best NZXT PC cases, the choice mostly comes down to two families: the airflow-focused H5 Flow and the dual-chamber glass showcase H6 Flow. This guide covers the best PC cases from NZXT that we could document with published specifications: the H5 Flow (2024), the H6 Flow and the H6 Flow RGB. Our research data only included these three NZXT models, so we are not padding the list with cases we could not verify. Note that we haven’t hands-on tested these cases: the picks below are based on published specifications and reviewer feedback, and prices are approximate ranges that change often, so check the current listing before buying.

What to Consider Before Buying an NZXT Case

Airflow versus showcase. The H5 Flow uses a mesh front built for airflow and quiet operation, while the H6 Flow models use a glass-faced dual-chamber layout that puts the build on display. If you care about the best PC cases for cooling and noise, the mesh front is the safer starting point. Radiator support. The H5 Flow lists a 360mm front radiator and a 240mm top radiator, whereas the H6 Flow family supports a 360mm radiator at the top only, with no front radiator. GPU length. The H5 Flow (2024) is listed at 410mm, and the H6 Flow models at 365mm, so measure your graphics card first. Fans. Included fans differ a lot between models and between RGB and non-RGB versions, so check what is in the box. White builds. If you are planning a white build, the H6 Flow RGB has a confirmed white variant at retail, which makes it a natural fit for the best PC cases for a white build.

Best NZXT Case for Airflow and Quiet Builds: NZXT H5 Flow (2024)

The H5 Flow (2024) is a mid-tower with a mesh front and a tempered-glass side panel. It supports E-ATX, ATX, mATX and ITX boards, fits GPUs up to 410mm, and has front USB-C. The non-RGB version ships with two 120mm NZXT F120Q fans, front and rear, while the RGB version is listed with a different front fan setup. Radiator support is 360mm at the front, 240mm at the top (280mm only with low-profile RAM) and 120mm at the rear. Prices run roughly $65-125 depending on the version and sales: one retailer listing showed the base model at $69.99 against a $94.99 list price, and the RGB version has been listed near $124.99.

Pros: Tom’s Hardware describes quiet and effective thermals, cable management is simple, and the case supports up to nine fans. Cons: A 360mm radiator does not fit at the top according to TechPowerUp, there is only one internal 3.5in bay, there is no back-connect motherboard support, and the non-RGB version has only two fans. Reviewers also mention just one front USB-A port. Best for: Beginners, quiet builds and anyone who wants one of the best PC cases for optimal airflow without spending much. Note that one source lists a GPU clearance of 425mm, but we used NZXT’s own 410mm figure.

Best NZXT Case for a Glass Showcase: NZXT H6 Flow

The H6 Flow is a dual-chamber mid-tower with a glass front, a tempered-glass side panel and angled intake fans. It supports ATX, mATX and ITX boards (not E-ATX), comes in black and white, and ships with three 120mm fans, color-matched to the case in the non-RGB version. It supports a radiator of up to 360mm at the top and a 120mm at the rear, and fits GPUs up to 365mm. The MSRP is $109.99, and sale listings have been seen between roughly $80 and $110.

Pros: The dual-chamber layout looks distinctive, three fans come preinstalled, and the 365mm GPU and 360mm top radiator support are enough for many builds. Cons: Back2Gaming notes that no rear exhaust fan is included, and some Best Buy buyers mention fan noise and heavy glass. We could not confirm front USB-C or dust filters for this model from our data, so check the product page. Best for: Showcase builds where the look matters as much as the cooling.

Best NZXT Case for a White Build: NZXT H6 Flow RGB

The H6 Flow RGB is the same dual-chamber idea with three angled 120mm RGB fans. It supports ATX, mATX and ITX boards, has a 360mm top radiator slot, a 120mm rear slot and no front radiator support, and fits GPUs up to 365mm. A white version is confirmed at retail. Expect roughly $115-135: NZXT sells it at $134.99, and one retailer listed the white version at $114.99 on sale.

Pros: A striking glass showcase in white, and Tom’s Hardware reported low temperatures thanks to the angled intake fans. Cons: The radiator fits only at the top, the 163mm CPU cooler limit rules out the Noctua NH-D15, and TechPowerUp found the RGB fans not very bright and the case pricey. Best for: White builds and showcase setups that want lighting included.

Which NZXT Case Should You Pick?

Choose the H5 Flow if you want the best value, a bigger GPU allowance (410mm) and a front radiator option. Choose the H6 Flow if you want the dual-chamber look and plan to add your own rear fan. Choose the H6 Flow RGB if you want that look with lighting already included, or a white build. Remember that our data did not include NZXT’s larger cases, so if you need more room than these mid-towers offer, look at the other case guides on this site.
