That case is an awesome case. Its the same one I used when building my computer. The included fans are pretty quiet and they keep the inside very cool (a lot of times i could touch the case and it almost felt frozen). It also looks super cool with the blue LED light on the front.
As for the hard drive, there are plenty of good ones out there, just find ones that get 4-5 eggs and are cheap. I can't remember what hard drive i got but it got good reviews on newegg.com and I found it for $10 cheaper on amazon
