|The NZXT H400i is only compatible with mid-ITX systems. The motherboard is placed vertically and thanks to the size of the case you will not have any problems with the installation of large heatsinks. The motherboard tray is made of solid steel, and it features a big cut out behind the socket, which allows the user to install aftermarket CPU coolers without having to remove the motherboard. The tray features a few openings allowing for neat cable management. Between the motherboard tray and the right side panel there is enough space to hide plenty of cables.
The case comes the latest features regarding internal layout and design, in fact, there is a big midplate covering the power supply and its cables. Overall, the NZXT H400i supports up to one 3.5" HDD and three 2.5" SSDs, both in dedicated places and well hidden. Behind the motherboard tray there are several cable routing channels which will help in case of cable management.
For our test we used an ASRock Fatal1ty X99M Killer motherboard and an AIO 240mm from Corsair and did not run into any compatibility issues, despite the small size of the case. Assembling a systems inside the H400i is easier than you might think. The area dedicated to the graphics card is large enough to accommodate even the most powerful GPU available on the market. After placing all the components inside the case you will end up with a clean rig. Although there are several thumb screws, most of them are way too over tighten and you will need a screw driver.
