The U.S. Department of Energy’s National Renewable Energy Laboratory selected Hewlett-Packard and Intel to provide a massive system for use in renewable energy research and related topics. Its $10 million machine will join an elite class with performance ranked at a petaflop–one quadrillion scientific calculations per second–and may attract even more attention for its claimed energy efficiency.

There is nothing new under the sun: They used water to cool DC and AC variable frequency motor drive SCR's for three decades. Also, the Control Data Corporation Cyber 7600 & 7400 had water cooling back in the 70's.

There was no 7400, and though the heat was carried away with water in the 6x00, 7x00, Cyber 7x , 17x and 7x0 lines, the actual cooling within the chassis was with cold bars with freon pumped through them. The heat was just exchanged with water which carried it away. I know of one site that cooled its Cyber by taking water from a well and then sending it down the sewer much warmer. The manhole cover there steamed like crazy in the winter!
This implementation seems as though the water may be more directly involved in the cooling, though there aren't enough details to be sure. I wonder what steps were taken to deal with electrolysis...

Regarding the CDC 7400, actually, there were at least 4 that I personally know of. There were twin Cyber 7400 model computers with quad stacked disk arrays at the USAF 6510 Test Wing at Edwards AFB, CA, and a matched set at the USAF Weapons Laboratory in Albuquerque, NM in the 1979-1983 time frame. I was an AF Computer Operator/Computer Resource Manager at Edwards AFB and operated those systems. At Kirtland AFB, the Weapons Laboratory had two as part of a 16 R&D computer capability which I was selected to design "connect" in one of the early computer networks as I graduated from the UNM EE/CE Department in 1983. So, I can personally vouch for the existence of at least 4.
