I think I vaguely remember someone saying something about removing a heatsink before putting a computer in a car, is this required? This is the first computer I've built with a high quality heatsink (ALX-800, supposedly lighter than the all copper ones) and I was wondering if damage could be done to the motherboard/cpu due to vibrations in a car trip? Would it suffice to put the computer on top of some soft pillows/blankets?
