Some years ago NCSA was selling off some retired 128P O2K systems really
really cheap.  I was only about 4 hours away from Urbana Champaign at
the time and was really tempted.  I was planning on running _lots_ of
seti@home processes on it, mainly.  ;)

The price was really decent for what I'd be getting, but in the end I
just couldn't justify it, no matter how cool it would have been to have
a dual rack 32P SGI Origin 2000 running in the basement, crunching S@H.

The reality check was that I could build a new 4U quad Xeon box at the
time, of about the same overall performance, and with lots more disk,
for a mere fraction of the cost of the used O2K.  It wouldn't have the
cool SGI badge or run IRIX, but I wouldn't have to add 220v circuits in
the basement, or acquire a big 220v UPS, or pay a much larger monthly
electric bill.

A single socket 12-core 2 GHz Opteron 6100 series on a SuperMicro mobo
with quad DDR3 memory channels w/32 GB RAM, sitting on your desktop,
would simply run circles around that old 2 rack 32P O2K system, probably
5 to 1 or greater in parallel linpack--for less than $2k.
