The one part of a system that a lot of builders overlook is the case, and it's a bad mistake. People get so caught up in what memory or cpu they're going to install that they overlook the case.
When shopping for a case, look for one that comes without a power supply. The PS's that come with cases are horrible and have no place in a performance rig like most builders are going for. I like a case that is roomy as well because I have large hands. I also look for a case that has rear and side vents to promote healthy air exchange.
I looked at the case you're considering, and it looks like a good one, but pictures are sometimes misleading. I buy all of mine from computer shows, where I get a good deal and I get to actually see the case as well.
Whatever you do, I wish you luck.
