Though the curves at the vertical panel edges are the biggest change to the revised case’s shape, the H6 RGB+ also gains a bunch more vent holes and a whopping four more fans. The right side panel’s profuse perforations are shaped into stripes and the name “NZXT” embossed and ventilated. And the curve between that panel and the adjacent 45-degree-angled fan panel represents the union between two parts that were separate on the 2024 version of the case.
The front connectors remain the same: two USB Type-A (Gen 1) and one USB Type-C (Gen 2×2) ports, and a four-pole headset jack that also works with stereo headphones. The new power button is larger and surrounded by an inward-curved bezel; the curve affords a better view of the illuminated power indicator ring.

The H6 RGB+ has just one removable fan filter. It covers the bottom air intake. The other intake fans rely solely on the very fine size of their cover panel’s perforations to capture incoming dust. The filter is removable from the side with the case sitting upright, but I had slight difficulty getting its leading edge to align with the three catch tabs on the case’s underside while reinserting it. Flipping the case on its side made it a lot easier.
Also, note in the image below that the middle screw holes in the fan mounts have no screws in them. That’s because the three intake fan-blade units here share a single 120mm-by-360mm frame.

A traditional inset PCIe slot panel lets PC builders drop graphics and other expansion cards straight in without having to finagle around obstacles, though it does reduce the case’s interior space from 16.2 to 15.6 inches. NZXT rates card clearance just short of that, at 390mm. Almost any modern card should fit just fine in here.
From this angle, you can also see that the power supply bay is directly behind the top of the motherboard, and that the back of the top panel has a tab you pull up to remove it. Look closer, and you might note that NZXT uses reverse-curve blades on all six of the intake fans (three side, three bottom) to conceal their motor frames on the side that isn’t showing. That’s a subtle touch well worth noting. The only fan here in standard orientation is the rear (exhaust) unit.

A group of access holes punched for an ATX motherboard’s perimeter allows the H6 RGB+ to support concealed motherboard headers for Asus BTF, Gigabyte Stealth, and MSI Project Zero reverse-connector boards. Additional holes above, below, and in front of the motherboard are designed to pass cables to the headers of standard boards.

Designed with a height-adjustment screw at the bottom and a damping pad on top, an L-shaped miniature card brace that protrudes from the front of the motherboard tray limits the maximum motherboard depth to around 10.8 inches when installed.

That might seem significant, since the case isn’t rated as Extended ATX. Given that most retail “EATX” motherboards are only 10.5 to 10. 7 inches deep, that removable card brace could be the only thing to prevent a determined builder from installing one here. Just know that since the forward-facing portion of that brace stands around 4mm proud of the tray, boards with deeply offset back-bracing/stiffening panels, like my 10.5-inch-deep Asrock X870E Taichi, won’t sit all the way down on the front column of standoffs. (Conversely, that motherboard’s backplate-free “Lite” version fits perfectly.) Proceed with caution if you plan to install anything bigger than regular ATX.

Also not on NZXT’s list is the case’s 280mm-format radiator capability, but you can see the extra row of fan mounts at 140mm spacing right along those of the rated 120mm spacing. With the H6 RGB+ having ample room (more than 65mm) between the top of the motherboard and the top radiator mount, most closed-loop coolers of typical 52mm-to-54mm thickness fit easily within the 410mm length of the panel’s interior.

One place you won’t be putting a radiator is behind the front/side fan assembly. There’s simply no space above or below the fans for the end caps of the radiator, which are necessary to hold fittings on one end and to redirect coolant at the other.

Slide tabs on the back panel hold the H6 RGB+’s drive cage between its power supply shelf and its bottom panel. Secured to those tabs via a single knurled screw, the cage can hold a single 3.5-inch drive on its inner portion and two 2.5-inch drives on its outer portion.

Behind the removable drive cage is NZXT’s Control Hub Lite. This module connects NZXT’s proprietary fans to the company’s own CAM software through an internal USB 2.0 motherboard header cable. Drawing current from our power supply’s SATA drive power cable, it also appears to add an ARGB input to enable motherboard ARGB lighting pass-through, though the case does not include an extension cable to reach any of those motherboard headers.
