im planning on putting a fullsized computer inside my car, a desktop in the trunk, 15" touchscreen LCD on the dash, mainly just somthing can do alot of wardriving with.... anyway, its obvious the inside of a car can reach temperatures of 120 degrees, in the daytime, should i be concerned about my parts being in this kind of heat when the car isnt in use? (i plan on making it water cooled so i dont expect problems when its running...) but when the computer is off should i be worried about the parts being damaged by the heat? if not is there a way that i can cool the parts when the car is off?
