What about making a setup like a Kegorator.

Get liquid cooling setup and daisy chain them together, take a small refrigerator or freezer and coil copper tubing into 50 ft coil maybe, drill 2 holes to run copper tubing outside the unit. Connect the ends of the copper tubing into the liquid cooling daisy loop to make a continuos loop. You may need to add a inline pump for circulation. Fill mineral oil or whatever goes in the liquid cooling setup.

Coinerator- Just an Idea
