Supercomputers with massive parallel CPU and memory arrays are often immersed completely in a chilled, non-conductive liquid such as silicone or mineral oil.
I propose the ultimate "case-mod" and overclockers dream: A computer case that manages to separate, contain, and seal all non-moving components
of a desktop PC in a tank of cooled liquid.
Vents that circulate the liquid through the tank would be strategically placed above key components, such as the CPU, memory, and graphics chips so that these parts would recieve the coldest blast. The liquid would then be expelled out of the tank and into another container, where it would be subsequently refrigerated and then pumped back into the PC.
Such a PC would be a nightmare to upgrade or otherwise tinker with as sealing the necessary components would result in something you wouldn't want to tamper with. I also imagine that at least a 5 gallon enclosure would be necessary to submerge all the right parts, not to mention what apparatus one would need to cool and recirculate the liquid.
Sheesh - why stop at chilled oil?

||Chilled silicone? I don't think that would circulate very well.
