ZDNetUK reports from the show.
The inside of this PC, from motherboard maker Foxconn, looks more like a refrigerator.
Not so carefully does it: supercooling a motherboard in the heat of a CeBIT exhibition halls requires regular top-ups. Luckily liquid nitrogen is a very good insulator so a little spillage won't harm the electronics.
Finally the Foxconn staff get the machine to boot, with an expectation that it will reach "something over 5GHz."
