well, it can be used to cool down heat emitting objects. for example its already being used to cool down ATMs. they use aircon laa..

well, the law of thermodynamics says that heat move to places where there is less heat. with good planning, the fridge won't go rosak. if its already cool, it'll stay at that temperature.

i say, go and do it!!!

and if you're considering sumthing else, try sinking your pc oil. they can cool your pc really well. and it has been done. can remember where i found it, if i do i can provide the link.

quad core is kinda expensive.. rm800 for the proc. if i'm not mistaken..
