Replace the power supply fan with one from Radio Shack (part no. 273-243,
$14.95).  Instructions for doing this were posted on the net some time ago,
but even without instructions it is obvious once you open the power supply
case.  The RS fan is 27 cfm as opposed to the original 32 cfm, but is so
quiet that you think something is wrong -- because you can hear the disk arm
positioning.
