Water cooling with no risk of damage?

I thought this was pretty cool. I saw it on TV a while ago, it's a liquid fire extinguisher that's not electrically conductive at all. It's called Sapphire. The pictures below don't show it very well, but I watched them take a running laptop, toss it into a fishtank full of this stuff, then use the laptop while it was completely "underwater". They took it out, and the stuff vaporises off quickly like isopropyl.

If you were running a water-cooled rig, using this instead of water would all but eliminate the chance of any water-related damage you might run into:

I wonder at what temp it freezes....

Water cooling? Just dunk your PC in a bath of that

How much is it

You mean like this

Mineral oil not whatever that stuff is. All you need is a non conductive fluid.

The issue with that is just because its non conductive doesn't mean it will flow through the blocks and whatnot easily. Let alone transfer heat like water.

Yeah, the other problem is switching out components as they will be all wet - attract dust quicker outside the case and i'm not sure things like hard disks could be inside the case? CD/DVD drives would definitely have to be mounted outside.

Yes...

Also I was reading some more, they were hitting 84C using that. The problem is its great to transfer heat initially but once the heat starts building up there is no where for it to go. You would still need that in a loop with a nice big radiator.
