Question for anyone with this case already..., have any of you had trouble with PSU cable length, particularly with the 20+4 pin cable? I'm getting a Corsair 750TX and want to route the cables behind the mobo first like in some of the pics here, just wondering if I'll need a few extensions. The 750TX's 20+4 pin is 58cm long. I think its plenty long, just kind of hard to judge from pictures.
