The CoolerMaster Centurion case is the best way to go.
Another suggestion is the Ultra Midtower that comes with a 500W X-Connect Power Supply(that had some bad reviews, I have n oreason why).(This case is 60 dollars at Tiger Direct)
If you want a clean computer dont buy any case that makes the Harddrive bays facing the side of your computer, it makes your wires VERY messy, and it is ugly. *Cough*RaidMax X-1(my case)*cough*
