That would be bad news for a few reasons, first why buy several watercooling kits, all thats needed is a bigger pump and a bigger raidator.Secondly, having 2 cpus at 3 ghz each does not give you a effective 6ghz machine. And why use up that much space? You can take a few microsized machines, using one large pump and raidator, and use them as a beowlouf(sp) cluster. All which you could fit ontop of a moderetly sized desk. But the question is why. I mean i under stand the bragging rights, but to me the thousands of dollars just isint worth it. There is almost nothing out there that will use that much power.
