well i didnt mean i was going to use water, i would obviously resarch a sutible liquid, but i mean idiotec, do mean to say that its a bad idea, im not sure if this is what you mean, but i think if i were to do it well and succsefully it would be awsome, the cpu would take a really long time to heat up that much water, and with the fans moveing the water around too as i said, with lights in it would look well cool, but yea you would be able to OC loads, providing i was able to keep the liquid at a low temp
