Space inside a chassis is essential for system builders as it highlights what components can fit inside and what cannot.
Due to 904’s width our test system CPU cooler extended outside of the case. This is rather unfortunate and disappointing – our Noctua NH-U12P is 158mm in height, most flagship offerings are around 160mm so this completely rules any compatibility with these devices out. There is up to 145mm available for coolers.
Limited clearance for air CPU coolers
Since there are no obstructions in the path of any PCI-E slot, 904 has good clearance for high-end graphics cards. Pictured is XFX 7970 DD which is approximately 10.5” in length – 904 can support up to 13”.
Good graphics card clearance
Behind the motherboard tray there are plenty of channels to arrange cable management. IN WIN provide just over 2cm of space between the back of the motherboard tray and the side panel glass. This is a reasonable amount of space and allows for good cable management practise.

904 is designed to house water cooling radiators outside of the chassis. The rear aluminium panel has a grid which, when combined with washers and screws can accommodate 120/140mm radiators. IN WIN has designed this especially for AIO type coolers.S
While this may be the only space for mounting such a device, we really like the idea, it transfers heat outside of the chassis and away from the system.
