Nice. Very genius way of dealing with heat.
More cheap than genius (but it does the trick) the rig cost me 12 bucks for a used cooler. For about 100 I could have rigged up copper tubing a small car heater core, a small water pump, a fan, the existing heat sink and some brass bushings as dielectric insulators between the copper tubing and aluminum on the cpu's sink and done liquid cooling (the Idea here is moving the heat away as quickly as possible of course it's probably not as efficient as a block but I'd bet it would be efficient enough) using some of my handyman skills, but I'm happy with the results I've gotten going this route.
