Just thought I would let everyone know what I did.

Motherboard: MCI865PE NEO-2P w/CoreCell
Processor: Intel P4 3.0Ghz 800mhz FSB 1mb cache(runs around 45-49�ºC w/fan, so I am thinking about water cooling)
Video Card: ATI Radeon 9200
HDD: Maxtor 120GB ATA133
Memory: Kingston 512mb PC3200 DDR400(to start with)
Sound Card: Sound Blaster Live5.1
O/S: Windows XP Pro
CDRW Drive: Yamaha 20x10x40x
DVDRW Drive: Sony (not sure about the read and write speed I got it out of another computer, but it works)
Logitech wireless keyboard and mouse
Power supply: 400W

I am going to rewire the case pwr switch so that I can turn the computer on/off from the front of the car. I would like to buy the touch screen monitor I saw on EBAY, but wasn't sure if it would be worth it.
Any ideas on how I to get cool air from out side the car into the trunk capartment?
