Geez, what kind of budget do you have?
Go with a big case, so you can get good airflow. I hear the Shark case (I think it is by ThermalTake) is really good.
Have you chosen a HSF? Surely, with all this, you're not thinking of using stock?
Monitor? Heck, go for twin 19" LCDs. The ViewSonic VP912b got BestBuy status in April's PCWorld. They list it at $560, and with a response rate of 12ms. They also gave the rating to the Dell UltraSharp 1905FP, at $529, with a 20ms response rate. The Dell has 3 USB ports and a "nicely designed thin bezel".
