The NZXT H6 Flow RGB is one compact Dual-Chamber chassis which can still accommodate an ATX board. However, at $140 for the RGB variant, it does feel a bit on the expensive side for what you end up getting. Other brands ask less for their visions of dual-chamber chassis to start out with, even before you look at the design and details within.

With that in mind, the one thing the NZXT H6 Flow RGB has going for it is the 45° corner where the three 120 mm fans have been placed. Whether it is due to those fans or the compactness and thus proximity of those units, the H6 Flow RGB also manages to perform well with this out of the box setup. On the downside, the provided fans don't really provide the same level of brightness with what appears a simple hub mounted RGB setup using a limited number of LEDs. At this point it is also worth noting that NZXT does brand these fans as F120 with a small note that these are case versions and thus actually different from the ones you would be able to buy separately, which isn't particularly transparent to the end user.

The NZXT H6 Flow RGB manages to fit a 360 mm AIO with ease, the motherboard integrates well, the GPU has lots of room as does the PSU, so from a build experience it is perfectly fine. But the case also has a theme of simplicity that sometimes goes a bit too far, which doesn't help justify the MSRP. From the simple RPM fans, to the lack of reset button, HDD activity LED or RGB/PWM controller to the large opening above the motherboard or the Velcro strips that will have a hard time really pinning cables down, it makes the case hard to recommend it over other options on the market that offer all that and more for less - no matter how clean looking and beautifully compact the NZXT H6 Flow RGB is in person.
