Most computers have a fan which sucks air through the disk drive. In a car you
probably won't have the fan, and the disk drive can certianly be put inside a
plastic bag, which will probably mean it will last longer than the drive in
your desktop pc (barring tempreture concerns).

The power supply will be a bit complicated. You need +12v, -12v, +5v, -5v
plus a few other lines (like power good). It could be easier to run a dc-ac
converter and use the standard mains power supply (lots of filtering in it).

For more information about putting pc's into cars. Do a search for MP3 players
in cars. They are putting hard drives in cars without too many problems. (the
other solution for the mp3 player is a cd rom drive to hold the songs with a
floppy to boot from.
