It's a 2u box, and there's plenty of ventilation and fans.  It's also
in a climate controlled room, so no external heat issues.  The
processors are in little supercoolers, and have never felt hot after a
crash.  Really scientific, huh? :)

This will be a wonderful weekend of hardware testing, whoo hoo.

Thanks!
