Probably a stupid idea but is it possible to submerge a PC in deionized water to cool it. I know the water slowly ionizes but could you work against that if you added a deionizing filter system to the whole thing. In combination with a sub zero cooling system it would solve all the condensation issues, add to the cooling and would be extremely beneficial for sustained loads due to the amount of water having massive thermal capacity. In my head this seems like the ultimate cooling solution.
Please explain why this wouldn't work...
