Sure enough, here's an announcement for Liebert's CoolFrame in conjunction with Egenera, whose blade servers employ a rack/chassis hybrid. In this case, it looks like product development consisted of finding the right size sheet metal screws to fasten the rack-top units on the back.

The initial press release called it "liquid cooling" (even though it uses refrigerant), which is not quite the spin I'd put on it, given the general aversion to liquids in the data center. Maybe they're trying to associate with the recent IBM Cool Blue and HP Modular Cooling System announcements, both of which use water.

APC, where are you??
