I had that idea a long time ago. Because I run two computers and two snake tanks in my room I can't get ambient temps cool enough to make water cooling worth while. After this year I will have an extra mini-fridge because I will be done with college. The plan is to buy a Lian-li tower and somehow refridgerate the inside. Screw condensation, I'm heading back to my old chemistry books to figure out temps and how to avoid it. I'm pretty sure though, that condensation happens when something really cold (a glass of water) goes below the environmental dew point temperature then the air around that thing condenses and water forms. So in theory, the only condensation to worry about is that on the coils which shouldn't be hard to keep from making everything else wet
