On top of all of this, I will need a 320-500gb hard drive(Haven't decided on 2.5" or 3.5" due to cold weather), and a slim-line slot loading cd/dvd drive

If I am missing anything, or you would personally go w/ another product to better suit the setup...let me know! The price I have it at right now as about my limit, maybe even a little above.

Intel DG45FC Part#BOXDG45FC -$130

Processor: Basically anything around 2ghz, 1mb cache...$75-$80

Low Profile Heatsink socket 775

CarPC Power supply: M3-ATX -$80 (Whats the difference between the M3 and M2, besides the new "design")

P4 Connector cable- Power adapter for intel mainboards -$10
