Hi, I read the thread about the way in which Comer tried to cool his PC by sealing the case and adding water to it. This obviously didnt work and infact turned out to be a windup in any case. So I set out to try and prove everyone wrong and actually see if I could have a working PC with the case full of water! So I started to do some research and came across a new waterproof spray called AquaStop. Have a look here: http://www.aquastop.org I bought a couple of cans to see if it would work. Now after many hours of testing I now introduce to you, the PC filled with water! (I added a few toy fish to make it look nice) It doesnt serve much purpose at the moment, as it isn't rigged upto a radiator or anything yet, but at least we know know its possible!
