Does the mobo have on board video?
You could use that instead of the AGP.
Depending on how your ram is setup, take out a stick?
*I* wouldn't put the dvdr drive in either. A standard one, maybe.
I dunno. I see no need for such a powerful PC (2.4ghz, 800FSB etc) in a car.
Unless your passengars are gonna be playing some games .
