Others have already made the joke that Fermi could double as a space 
heater, but I wonder if that could end up being reality..  It's also not 
really breaking news that a water cooled system is more efficient than 
air, but how real world tested is this?  From the pictures on the 
youtube video [1] I wonder how this could be adapted to the current 
trend moving away from cell and towards gpus..  (The conduit looked 
pretty well mounted to processors which would be much harder to do with 
a vertical PCIe card...  Not to mention leaks..)
