BUILDING THE SYSTEM
As always the purpose of this section is not to build a functional system but rather to showcase what you can expect from the case at hand in terms of interior space.
If you remove the PSU area cover using a standard ATX mainboard doesn't seem to take too much space (since this case can accommodate even E-ATX mainboards that was expected).
COUGAR has made it possible to mount CPU Coolers up to 170mm in height so that means 99% of all of them in the market.
You also have enough space to mount four 390mm long graphics cards and as you can see the GeForce GTX 590 leaves quite a bit of free space.
Using a very long PSU will cover up both fan areas at the bottom of the case.
The PSU cover can help hide some of the cables and it does improve the looks of the interior.
