One of the computers that had a VERY bad airflow was the Tandy 2500SX.
They used to have one at my school, and someone left it on over the weekend
(turned off the monitor and forgot the computer). When they got back on
Monday, the fan in the P/S had stopped (bearings had somehow frozen), the
HD was still going, the top of the case (plastic) had gotten soft, and the
monitor had sunk into the top of the case. The hard drive was an old
Microscience 72(? may have been 80 with a lot of bad sectors) MB that
sounded like a full-height Maxtor when it was running. Nothing worked
anymore, except the HD would spin up. It was the only computer from that
school that I couldn't revive. Not even the RAM chips worked anymore.

Would excessive heat caused the bearings in the fan to freeze? The fan was
working when the computer was turned on, but was totally frozen (VERY tight
when removed from P/S) on Monday. The computer was a mini-desktop, and
only had a few vents near the bottom of the front panel and only a 2 1/2"
fan.
