Once I have a whole new build I could care less what happens to my old one. I can't think of a single reason not to build it in an aquarium. Hilarious is hardly the word for it, I'm thinking awesome.
And done properly, an oil submerged system can last for years.

Also, Jarnis thanks again for your input. I lapped my heatsink and reapplied thermal compound and managed to get my cpu temps down to low 50's from low 70's. My 3dMark score went up to 3900, and Dragon Age is running great. Do you think lower temps yet will continue to improve the performance? At what temps does the heat start to affect my performance?
