This thing looks like it takes water cooling very serious. I did not know Hitachi is into making water cooling systems.
The new self-contained thermal solution is going to be used with two AMD Opteron 2220 (2.8GHz) processors in a HP xw9400/CT Workstation.
Apparently HP is only selling the water cooling solution Japan.Water cooling becomes more and more common. It looks also the systems get more compact like on this BFG 8800 GTX or in the Water Cowboy PC ATX supply.
More details on Frostytech and on Watch Impress (Japanese).
