I personally feel that the bitfenix is a great choice for a PC case.
Looks (subjective) = check.
Cooling = 2x 230mm fans, and availability for 3 additional 120mm fans to be installed. Push-pull system. Specially designed space for water cooling system.
Feautures = Integrated Fan control and light control on original colossus. Lockable compartment holding front USB ports and system control buttons. USB 3.0 on front in original colossus. Pulse option for lighting. Light colour switching on the fly (2 colours) on original colossus. 8 expansion modules.
Easy to build in = integrated cable management system. Thumb screws. Massive, so many options for expansion. Can take all modern parts of all sizes.
Made of highest quality = Softouch Rubber, steel and plastic. I won't argue when people say that plastic isn't the highest quality material, but as far as I'm aware, the plastic is only on the Windowed version.
Overall, I love this case
