hmm.. never thought about useing CO2 to cool my cpu before. i have it for my MIG welder so i always got a couple of BIG tanks of the stuff lying around. :) it would probably be posible to use it to cool the cpu, the botle and regulator gets ice forming on it when you use it for welding and that is only venting it to atmosphere at about 30psi.
and yes, i am in the UK, wales to be more precise. :)
