No idea. My quad weighs over 100 pounds, however. So it could be an industrial-strength cabinet, + power supplies. IE my quad has 3 450 watt power supplies which are very heavy. It is possible that the machine being used has bigger supplies, plus a large hot-swap cage for disk drives. As far as the price goes, it is _way_ overpriced if the quoted price is really accurate.
