At these densities, I'd rather just say that you sell a "hot product";-)

Interesting.  Vertical case mounts and nifty control features, hmmm.

Well, ok, so it is very clear -- current CPU/FLOP densities have reached
well over 10 KW per rack footprint.  Install one of these in your
basement and keep your house toasty warm all winter long for a mere
$500/month or so in electrical costs (at $0.07/KW-hr).
