This is my first go at water cooling and I'm going to start putting my system together in a few days. When this is all completed how would you empty out the system. Since my radiator will be mounted externally I was thinking of disconnecting one of the hoses and let the pump push or pull the water through the loop ad drain into a bucket. Since I'm using the DD 12v pump connected to my power supply don't I have to have all my components (HD's, MOBO, etc) plugged in inorder for the PS to work? I don't want to do this because the system would be running without water for a brief period.
