  Several years ago one of the people in our "terminal repair" service
(which does all PC's monitors, etc) studied the failure rates of
equipment and concluded that the failure rate per unit per year was
30-50% lower if the equipment was left on all the time. Turning stuff
off over the weekend had no significant effect, but daily power cycles
hurt badly.

  Of course any systemn which runs UNIX will probably be on all the time
for mail/news etc, but the monitor can go off on weekends.

  This was true of equipment in use at GE at that time. You assume
responsibility for any projection of that data to your situation.
