Not a bad PC at all, but I wouldn't go to Microcenter for everything. Just the CPU/Mobo and RAM (if they give you a package deal for the RAM - I think they do with the one you picked). Although I'm not sure how you found that video card for $315??
On the case, if you're getting a bargain case, do some shopping around. The 210 isn't awful, but the HAF 912 is probably the best in the sub-$70 market for cooling and fitting everything easily. Not that I particularly care for the aesthetics of CM cases (I do not).
