Introduction, Specifications, and Pricing

It appears that NZXT is on a mission, with the all-new H6 and H6 RGB+ dual-chamber mid-tower cases. These new cases are using what NZXT calls its new design language to define its next-generation products. Apparently, this isn't just a refresh, but a statement of intent about where NZXT is heading. The H6 and H6 RGB+ introduce a bolder design, smarter solutions, and a commitment to bringing genuinely new ideas to the PC building space, modernizing the original H6 Flow.

While the standard H6 will retail for $99.99, the RGB+ version bumps the price to $199.99, and both are available in black or white variants. NZXT is positioning these new cases as their compact dual-chamber option. For a larger dual-chamber build, you have the H9 Flow, and for a more traditional single-chamber layout, the H7 Flow or H5 Flow provides alternative options.

The price difference between the cases comes down to what is, of course, included. The H6 is available only as the case, with no additional fans or controllers, providing a blank canvas for you to fill with your choice of fans. The H6 RGB+, on the other hand, comes loaded with pre-mounted fans, two F360 RGB reverse single-frame fans for intake, and one F120 RGB fan for exhaust. NZXT also throws in the Control Hub Lite for unified lighting and fan control via NZXT CAM software.

Today, for review, we have the NZXT H6 RGB+ version to check out, with NZXT also including some extras that we will cover later on in the review. With angled fans, fine mesh panels, BTF compatibility, and curved glass, there is a bit to cover today, so let's get into the unboxing.

Packaging

42

42

Packaging for the NZXT H6 RGB+ is fairly basic, with a brown box and black print used. One side displays the NZXT logo at the top and the model information at the bottom. On the other side, it's really plain, with just a full-color sticker in the top right showing off the case and model.

42

Both ends are basic too; the only thing to note is a QR code link to the product manual.

42

Things don't get any more exciting when I remove the case from the box. It's well packaged, with closed-cell foam pieces on the top and bottom and a bag for dust protection. This is the industry standard for packaging, and our review sample arrived safely.

Outside the NZXT H6 RGB+

42

Stripping away the packaging, I get the first look at this new case. While NZXT markets this as compact, it still takes up a bit of space, measuring 420mm x 292mm x 448mm (L x W x H). It is a nice-looking case, and NZXT tells me in the reviewers' guide about some of the key changes. This generation's changes include seamless curved glass and 120mm fan standardization, so no 140mm fan support. They include a GPU anti-sag bracket, back-connect motherboard compatibility, an illuminated NZXT logo, and updated mesh treatment. The 360mm top-radiator support and the overall dual-chamber build are retained from the previous generation. I must admit I do like cases where every fan placement is identical, or offers both 120mm and 140mm variants. Some cases use 120mm predominantly and a 140mm for the rear exhaust, so keeping fan sizes the same regardless of size is nice to have. NZXT offers a 2-year warranty for the 55L volume H6, and it weighs 9.3kg / 20.5lbs.

42

Let's start our case tour then, with the tool-less top panel made of steel and featuring fine mesh across the front chamber. This panel also shows off one of the NZXT H6 RGB+ main features, too, the angled front corner that we will show more of soon. Color matching across the steel and plastic components looks well-matched, too.

42

42

Viewed from the front, you see more of the angled corner, and it sort of reminds me of the Flat Iron Building in New York. It's nice to see something different in terms of case design and trying something a little different. HYTE did something similar with the Y60/Y70, albeit with the other corner, using glass to complete the transformation rather than a mesh. That is part of the functionality of the H6, given the fan placement.

I/O is standard for 2026 and well laid out. NZXT includes Power, two USB 3.2 Type-A ports, a single USB Type-C port, and a headset jack to complete the layout.

42

42

The rear panel features a solid border and fine mesh used for the large central area. This should allow for plenty of air to be pulled into the front-mounted fans and the power supply, given the dual-chamber layout. Good clearance to the bottom-mounted fans is provided below the curved grey plastic trim.

42

If you missed it in the above photos, the NZXT logo is also imprinted on the rear-panel mesh, along with other smaller recessed areas. It's a small detail that is easily missed because it blends into the rest of the case panel, but it's nice to have something that isn't completely flat.

42

Moving my attention to the rear, the dual-chamber "default" layout is presented. Not many cases deviate from this layout, simply because it works well. An ATX Power supply mount is located at the top right, the motherboard I/O sits in the middle, before reaching the rear case fan on the right-hand side. There is no height adjustment available for the fan, which is a bit of a shame, as it would help it line up with an air cooler if that is what you are going to be using.

Below, seven PCIe slots feature tie-down points to the left. The lower left-hand side features tabs to locate the internal storage caddy under the power supply. Venting surrounds the front chamber of the case, while you will also note the lack of thumbscrews; all panels are tool-less on the H6, regardless of variant.

42

Lying the case on its back, we have a good view of the underside. NZXT employs a full-frame dust filter over the bottom-mounted fans. The filter is magnetic and slides out from the side, so the case doesn't need to be tilted to access it.

42

42

Removing the filter reveals the fans and mounting holes. The feet of the case include rubber pads and are elongated to match the case's angles. Just as the back has good clearance, the front matches with more grey trim.

Inside the NZXT H6 RGB+

42

Time now to move on to the interior. With the top panel removed from the case, you get a good view of the top AIO/fan mount. While NZXT lists the H6 RGB+ as only supporting 120mm fans, the rails appear to support 140mm fans. However, there is no note of this in the reviewer's guide. The rear chamber also has a cutout for access, but the top panel doesn't include ventilation over this portion of the case.

42

Showing the underside of the top panel, no dust filter is included, but I would opt for a bottom-to-top, chimney effect cooling solution on the NZXT H6 RGB+, with a top-mounted 360mm AIO. In this configuration, a dust filter isn't required and would only impede hot air from escaping.

42

42

Time for a full frontal, and the interior is lovely. Removing the tool-less glass panel was easy and gives good access to the rest of the case. All major BTF motherboards are compatible, and the H6 can accommodate up to 10 120mm fans, which should be more than enough to keep a system cool. The included 2 x F360 RGB Reverse fans will run up to 2,200 ± 220 RPM, and the rear F120 at 2,400 ± 240 RPM. CFM varies slightly, from 62.14 per fan on the 360s to 70.76 CFM for the rear.

42

Another angle of the case interior shows the well-placed cutouts for cable pass-through, or, of course, with a BTF board, the front chamber should be fairly free of wire clutter. The motherboard tray includes a large cutout for cooler installation and features a rounded corner at the front edge, where it meets the back of the case and the front-angled fans. Two screws towards the bottom of the motherboard tray hold the Control Hub Lite in place in the rear chamber. This is fine, but if you ever need to remove it, you'll have to remove the motherboard to access these screws.

42

42

Using the dual-chamber design, this keeps the hottest components isolated, while the angled front fans provide targeted cooling to the GPU rather than the glass. NZXT is aiming for better thermals, a cleaner look, and more airflow to where it matters. Another deviation from the H6 Flow is the placement of the backlit NZXT logo, while it won't be to everyone's taste, NZXT has included it at the bottom left edge of the front.

42

42

NZXT is next up on my hit list of GPU anti-sag bracket implementation. There is some height adjustment, which should be useful for longer cards, but again, it could do with some work, like so many other manufacturers. The H6 RGB+ also includes some side-mounted pass-through points on the motherboard tray, for routing cables to where they need to go.

42

42

42

With the rear chamber exposed, you can see the layout. The H6 RGB+ includes Velcro tie-down points along the top and left side, and the rolled edges of the cable pass through points are nice and smooth. As with the top, the rear side panel doesn't include an internal dust filter.

42

42

Concentrating on the lower portion of the rear chamber, the included drive sled can hold two 2.5" drives and one 3.5" drive. A single thumbscrew holds it in place, and once removed, you gain access to the Control Hub Lite. All the included fans are connected here, and, being single-frame, each unit has only a single connector. 99% of the wiring is color-coded to match the case, with just the controller connectors being black.

42

To round out the internals, a view into the top of the rear chamber shows plenty of room to run excess cables and keep them tucked out of the way. Of course, if you don't need the drive sled, this can also be removed to free up more room, but the back chamber is fairly spacious, even with it included.

42

NZXT includes a paper manual, and the included accessory box is fairly basic, but it includes everything you need to install a full system in the H6 RGB+. With the case now covered, we can move on to testing.

Test System, Installation, and Finished Product

42

The installation process should be fairly straightforward, and that is certainly true with the NZXT H6 RGB+. There is plenty of room to run all our wiring, and thanks to the access around the front, nothing threw a spanner in the works. All in, I think it took around ten minutes to get my test system installed. There is still room to play with around the back, and if you take out the storage caddy, you have space to add any extras you want to the system.

42

Around the front, with the system fired up, it comes to life with the included fans. Time then, to set up the fan colors in NZXT Cam software and get testing.

The system I have built for testing includes an AMD Ryzen 5 9600X CPU, housed in an MSI B850 Tomahawk Max Wi-Fi Motherboard, paired with two sticks of 16GB Corsair Vengeance DDR5-6000 memory. Our CPU is kept cool using the be quiet! Dark Rock Elite. For storage, I am using a Corsair MP700 Elite 1TB NVMe M.2 drive. Finally, for graphics, I have an ASUS Prime RTX 4070 12 GB Super. Testing is completed with PBO enabled, AXMP1, and MSI Smart fan configuration.

All testing was completed using Aida64 Engineer's System Stability Test v7.65.7400 for 2 hours. Other software used was HWiNFO 64 v8.34-5870, TechPowerUp GPU-Z v2.68.0, and CPU-Z v2.15.0 x64.

Kris' Test System Specifications

42

It has been really warm here in the UK, and I am ready for a rest from it! Being so warm shot the ambient up to around 25 °C, and it will certainly make our little system work harder.

Our AMD 9600X ran at a maximum of 78.9 °C, settling to an average of 76.2 °C over two hours. When testing cases for TweakTown, I have seen these values range from 65.1 °C to 81.4 °C, and when temperatures are normalized to 20 °C, the NZXT H6 RGB+ performs rather well. Sitting mid pack on my spreadsheet, the H6 nestles between the Endorfy ARX 700 and the Montech King 45 Pro. Given I ran an air cooler for testing, an AIO would drive these numbers down even further, so take these figures as a baseline that can only get even better.

Casting my eyes over GPU results, the NZXT H6 RGB+ shot up the charts to second place overall, behind the Antec Flux Pro Noctua Edition. Values from testing ranged from 69 °C to an average of 68.1 °C. When normalized, the average was 63.1 °C. The results for the GPU are great; the positive pressure created by having six intake fans and one exhaust helps, along with the bottom fans being directed straight at the GPU. NZXT has done a great job with this case.

Final Thoughts

Before I draw my conclusions on the NZXT H6 RGB+, NZXT sent over some extras, so I threw them in to see how they look. Along with the H6 RGB+, NZXT is launching the all-new Ultra fan sets. The new fans introduce multi-zone RGB lighting, giving users control over distinct areas of each fan, including the hub, outer track, and, on single-frame models, bar lighting. Dynamic lighting flows through the independent zones for fully customizable visuals. Single-frame models are also designed to simplify installation and reduce cable clutter.

NZXT includes a five-year warranty on the fans; they are available in black or white, with pricing as follows:

F120U $29.99

F140U $34.99

F360U $89.99

F420U $99.99

NZXT also sent over a Kraken Elite 360 RGB to finish out the all-white look, so let's get these installed and see how it looks.

42

42

Swapping out the included fans was easy, with only four screws required on the 360 versions, followed by a simple cable run back to the control unit. Having three lots of cables run through a single connection makes the building so much cleaner and easier to manage. With the Kraken Elite 360 RGB installed and up and running in NZXT Cam, it's a great-looking system, let down by a black motherboard!

Time, then, to wrap this one up and share my thoughts on the all-new NZXT H6 RGB+. I've mentioned before that some case reviews can be longer or shorter, depending on whether they focus on the good or the bad points. Here, there isn't much to cover on the downside, aside from the GPU bracket, which is a small issue that can easily be resolved.

Moving to the good stuff, there is plenty going for the NZXT H6 RGB+; it's very well built, and while the angled front won't be for everyone, I actually quite like it. The case performs well, that's clear from the testing carried out, and it's easy to work in, very easy indeed.

This case offers performance and value, having seven fans included for $199. Take the Cooler Master Master Frame 600, for example: it costs the same, has fewer fans, and performs a little worse. The Corsair 5000D, again at the same price, has fewer fans but has around the same performance, so you can see where this sits. Overall, I would have no problem having this sat on my desk long term; you can fiddle with the lighting all day in NZXT Cam and have it as a focal point, showing off all your hardware. Sometimes wrapping up a review with less, and not more words isn't a bad thing, and that is certainly the case here. Good job, NZXT.
