Submerged computers

Its pretty neat, but you don't want to let the oil get too hot otherwise you could fry the whole system.

i kid, i kid.
Always wanted to try this out, but I just lack the resources to attempt it.

Oil's flashpoint is 425F. If a PC part is reaching that temperature, it is not a PC part, it is a melted pile of components anyway.
Anyway, yeah, this type of cooling is something I've always wanted to use since I never resell my parts anyway; I use them for 4-5 years anyway to the resell value on a 500 dollar item is like 5 bucks anyway. I've seen some people that put fake fish in it and make it look like an aquarium haha.
