I have two primary computers. One runs the home theater, the other is my "work" setup. The HTPC was built primarily to play games and be very quiet without resorting to water cooling as I did for the old gaming rig. It is comprised of the following parts:
Zalman HD160 HTPC case
Asus P5WDH-Deluxe MB
Intel Core 2 E8500 CPU
Nvidia 8800 GTS 640MB video card
4 GB Corsair PC800 DDR2
3x Western Digital 500GB RE2 drives running RAID 5 (1 TB of storage)
Zalman 600w power supply
LG Blu-Ray Player
The HTPC drives an Optoma H78DC3 projector and fills a 106" screen (more details on the home theater page)
