Does anyone own this case or has anyone seen it in action? I've only heard good things in the reviews I've read. I was just wondering how good for cooling it is, how good the air flow is. As in, if I put a 7800 (and lots of other things of course) in there, would it block the flow too much? I think there should be enough room for all my parts though. And could I fit a full size PSU in there or do I have to stick with the one that comes with it?
