A Closer Look – Exterior
NZXT has a design philosophy that can be seen throughout its entire product range. From power supplies to gaming mice, it’s all built around black or white, with matching holes for style or ventilation, matching RGB technology, etc. This means that whatever case, motherboard, cooler, and other NZXT hardware you put together, it should match up perfectly. That’s still the case with the H9 Flow, with that ultra-clean design really making this thing pop. If that’s not enough, there’s also a dual tempered glass window, with glass on the front and side, and a pillarless front corner for uninterrupted views of your hardware.
On the left side, there’s excellent ground clearance on the sides, allowing for plenty of airflow to any bottom-mounted cooling.
On the right side, there’s even more airflow, with front side fan/radiator mounts at an angle; these are basically on the front of the case, but turned to the side a bit to allow for the front panel glass and better visibility of your build.
There’s further airflow towards the rear, ensuring components like the power supply and storage bays get all the cooling they need.
Then on top, there’s a massive amount of ventilation here, allowing for additional fans and radiators. Between the front side, top and bottom of the case, you can get 9 x 120mm or 140mm fans in here, so yeah, airflow really isn’t going to be a problem here.
Around the back, you can see this case is split into two chambers, with the rear section housing the ATX power supply mounted on its side, and some storage bays below that. On the business side, there is the ATX motherboard rear I/O, as well as seven expansion slots.
The expansion slots are all metal, ventilated and reusable, but strangely, don’t have the option to rotate the mount vertically, even though there’s enough width here. However, there are no horizontal bars between them, so ATX vertical mounting kits will still be compatible.
There’s a 120mm fan mount at the back, with extremely long screw mounts allowing for significant amounts of height adjustment. This is going to improve compatibility with some coolers, especially if you have a very thick radiator at the top of the case.
The PSU is mounted a little high up in the case, but there are two cable tie loops here, so you can strap down the cable and keep things neat and tidy.
