	Greetings...Have to add my two cents worth to the cooling fan
discussions...

	I have had my IIe (with 6 slots full) running 7 by 24 for four (4)
years and have lost one power supply (the Apple original).  I replaced the
supply with an AE device of higher power rating and "tacked" a Radio Shack 12
volt D.C. fan across the Apple 12 volt line; then placed the fan up against
the back side of the case blowing into the slots where cables exit the case.
No problems since then (1 year of 7 X 24).  I had also lost three (3) I/O
chips on a home-brew speech synthesizer board which I attributed to heat build
up.  Like big mainframes the Apple seems to like one mode of operation, i.e.,
either leave it on all the time or use it for short durations, not a mix of
the two.  Since my machine is used for home-control it MUST be reliable,
available and recover from power outages, etc.  The basic box is pretty good!
