   I haven't run the Cray all that much since I've lived here, due to 
lack of fundage.  They were the worst offenders heat-wise.  Up in 
Maryland when I was running the J90 full time, I had an 18,000 BTU air 
conditioner handling the machine room.

   Here (AS500, AS800, AS4100, box full of FC-AL disks, rackmount 
Ultra60 with lots of disks, E450, a couple Netra-X1s, a couple Ultra1s, 
and a Cat5000 running full-time in the machine room) I have an 8000 BTU 
air conditioner handling them.  Barely.  Upgrading that is very high on 
my priority list.

   It never really gets cold enough here to make use of "mother nature" 
air conditioning.
