Yikes!

Heh.  I'll have a little holder sticking out the front to keep my coffee
cup warm,  while I'm at it.    There's something really wrong with
them jamming that much stuff into that small a space and trying to get it
to dissipate that much power...

I'm not convinced that multiple CPUs might not be a better way to go, 
anyway,  I don't have any single application that demands that much CPU
horsepower,  can't imagine anything I'd want to do here needing such a
thing.  And those who do (animators,  for example) seem to be moving to
arrays of lower-grade machines,  running linux.

Weren't some of the Cray machines liquid-cooled?
