The ultimate computer case. I mean ULTIMATE!

The bottom half of the tower is a Mach II phase change cooling system, which for everyone else means it has a refrigeration unit that's powerful enough to cool a large refrigerator. This model is only to cool your cpu, but there is a company that modifies them to support two video cards for crossfire and SLi support.
Normal operating temperatures are between -50C and -20C depending on load and the heat coming off of the processor.
I'm planning to invest in one of these very soon and hopefully will be able to either a) have my neighbor modify it to work with a processor and two video cards, or b) buy a ready made version.
Here's a review of the newer Mach II GS system
The pc building bug has bit me. :chimp:
