I ate them.
Yeah, i run several games to get my pc temperature up so high it melts the casing (yes metal casing) and then when the case is completely melted, i unplug the computer and start eating the cd drive, which is cooler than the motherboard, my next meal.
Depending on the computer, i sometimes might not be able to finish it so i put it in my freezer and plug it in the next day.
