Its good to note that not many cases allow for all the 3.5 or 5.15" bays to be used with water cooling, a pump, tubes and a radiator take up a lot of space!
So what do enthusiasts do? Either design well routed case systems from scratch, or use REALLY BIG CASES.
I've used the armor in builds before, and its really big, but as the author implied, its construction is nothing really to rave about.
I use a Lian Li PC-V2100 PLUS II with an HE120.3 mounted to the top, and I have only lost one 5.15" bay of 6, and still have 12 3.5" bays for HDD's

(6 of which are filled)
Due to there being dual PSU space, you can fit the pump above the first PSU, and lose no extra space (unless you are building a workstation and want that slot :O)
