I would suggest either the Thermaltake Shark, Armor, or the ANTEC P180. I was going to get the shark till i noticed that the P180 had 6+ fans and there moovable...that means you can position your larger top fan on ur CPU and your other large one on ur GPUs (SLI) or on your HDD (mine are three WD 100gb Raptors @ 10,000 rpm...reason for this is one for the system and proformance driven programs, one for music and movies....LIMEWIRE r0cks!....and one for World of Warcraft and Patches and Add-ON UIs, a lil large but VERY efficient in RAID)
