Yeap, already looking at Co-location datacenter services for em right now. Just got to find a Server PSU that can run three of em at once. I take thought some guy was claiming to be an official IBM reseller with a setup that had no bare wires which could handle the load.
The IBM 2880W will be able to run 2 of these, I'm not aware of any common PSU that will be able to run 3 at their claimed power consumption (that would be 3,390W DC total). The ideal layout would be powering 7 S7's between 3x IBM 2880's, it would put current draw on each PSU @ 2640W, leaving it around 91% loaded. J4bberwock is the developer for the 2880W breakout boards, I am his partner/official re-seller for North America.
