A Closer Look - Outside

From our usual angle the NZXT H6 Flow RGB looks quite similar to most other dual-glass, dual-chamber enclosures, but as you will see below, that is far from the reality of things. The one noteworthy aspect of this chassis is its size. The H6 Flow RGB is one of the most compact ATX cases of this style out there. Even though the spec sheet mentions "dark tinted glass" for the black variant, it doesn't really appear to be heavily coated so you should still be able to see everything inside the chassis with ease.


Looking at the enclosure from the front, you can clearly see the unique design element. NZXT has angled the fans which are usually found on the side of the chassis by 45° to aim them into the middle of the enclosure. This should help direct airflow towards the GPU, while still giving the aesthetic of glass wrapped around the front of the chassis. In the rear everything looks pretty traditional for a dual-chamber chassis, but NZXT has opted to put the PSU at the top, whereas most of these have the unit at the bottom to reduce any potential cable clutter.


The main side panel is all glass, which is framed cleanly in black with a singular thumb screw and pop pins holding it in place securely. The opposite side is made of steel, but NZXT has also finely perforated the majority of it to allow for airflow while also keeping dust out at the same time.


The IO consists of a combo audio jack, USB-C, two USB-A in the traditional purple we have come to expect from NZXT as well as a power button with LED illumination around it. There are no controls for RGB nor is there a reset button. While NZXT has also opted not to label these, all the IO is pretty apparent and doesn't need it. The angled panel is also made of metal with fine perforations to act as a dust filter while allowing access to fresh air for the fans. There are three 120 mm intake units pre-installed. As this is the RGB version, these have embedded LEDs as well.


While the overall build of the NZXT H6 Flow RGB is simple, it does feel functional so far. The rear sports seven gapless expansion slots with individual, reusable covers. Above that, there is a vented section with elongated mounting holes for a 120 mm fan. On the left side, NZXT employs a classic hooks and screw combination to hold the internal HDD cage in place, while the PSU bay is simple but effective with two sets of mounting holes, so you can choose which way your power supply gets installed. There are several hooks for zip ties going down the back of the case, which is a nice touch to allow for clean cable management on the exterior of the chassis as well.


The top continues the trend of metal paneling with fine perforation pulling double duty as a dust filter. You may remove it to reveal mounting holes for a radiator of up to 360 mm in size. Alternatively a 280 mm will also fit, or you could go for the same number of 120 or 140 mm fans instead. Interestingly enough, there is a third row of mounting holes, which would suggest that you could install even larger fans here, but the spec sheet of the H6 Flow RGB does not mention it, so you can try at your own risk. If you look closely, you will see that there is plenty of room above the motherboard tray, so your liquid cooling setup should easily clear any internal components.


On the underside of the H6 Flow RGB, there is once again a section of the floor paneling which is perforated finely. Here you may install two 140 mm fans on rubber ring equipped mounting holes. This is a nice touch, as these are actually recessed into the floor as we will see later on. It is interesting to see, that NZXT has opted to skip the ability to use 120 mm units here altogether. Besides that, the trend of simple but functional certainly continues here as well.
