Building Advice

I am building a new gaming computer and want to make sure my major components are all compatible and need some suggestions of a case.

CPU: Intel Q9550 Yorkfield
Motherboard: Asus Rampage Formula LGA775 X48
Video Card: Diamond 100243-1GL Radeon HD 4870 1GB
CPU Cooler: Thermaltake V1
Disk Drive: LG Black DVD Burner
Memory: Crucial Ballistix 4GB (2 x 2GB)
Hard Drive: Western Digital Caviar
PSU: Not Sure How Much I Need


I need to know again if they are compatible, if that would be a good combo, and what case will be able to fit it all.
