I got a small fridge given to me (24" x 24" x 24"). Do you think it's cooling capability can handle a Pa 120.3 and CPU/NB/GPU setup?
I'd put just the fans and the rad inside the fridge.
Condensation could be a worry since we run evaporative cooling in the summer. My ambient summer temps are as high as 30 C. (high humidity). My comp is on 24/7 so I wouldn't have really cold water to the comp.
It's a way to reduce my ambient temps a lot in the summer.
