My custom box
 

Here is a pic from an article I wrote a little while ago about my main WC rig. The box is cooled by a radiator and pump/reservoir that is mounted remote. (It is right behind the top of the PC in the picture below, it sits on a skid to the right of the desk and is built to handle 3 PCs in all, each with their own rad and fan setup feeding from one pump.) The coolant travels through high pressure spiral tubing that allows the PC to be moved to any angle and avoid spills. I used high pressure back-check quick release connectors for the water lines as well.
