Computer submersed in water?

[13:02] Chruser: Speaking of which, I still want to put an old computer in deionized water and run it. [13:02] Chruser: In theory, it should work. I disagree. You can remove the ions from water, but the water itself will form ions by decomposing into hydrogen and hydroxide. The computer might even cause the release of hydrogen gas then ignite it

Actually, if your computer is not filled with dust (i.e., it's free of contaminants) and it has a reasonable amount of flow of new deionized water, it would work just fine. I remember reading about some guys submerging a computer (dust and all) in deionized water and it worked for 5 minutes. Theoretically, it could last indefinitely with the right setup.

But it's not very practical, and there are better alternatives.

EDIT: Oh, and the idea that the computer would cause the release and subsequent ignition of hydrogen gas is just absurd.
