With regards to the fan issue:
	A 2" biscuit fan mounts quite nicely inside the upper right rear corner
	of the Mac+ chassis, along the top panel. (Looking at the machine from
	the front).  Simply pop-rivet the fan in place with the orientation to
	force air OUT of the adjacent vent and you have a very inexpensive way
	to reduce the thermal load on the power supply.  12VDC can be found on
	the right-most yellow wire in the power bus coming from the video board
	to the mother board.  I used a long pair of wires and a molex connector
	to allow easy removal of the case and hookup of the fan.  To reduce 
	noise, you could cut out the section of adjacent vent in the forced-
	air path.  In any case, you should block off the rest of the vent
	on that side of the case's top panel to reduce shunt flow.
