Well, I shutdown the system again (have you heard this phrase from me or what?)
and reassembled it.  Turned it on and no boot.  We then quickly ripped the
top off to measure the power supply levels and we found a problem.

The voltages were the same as I mentioned in my last posting.
EXCEPT the -12V (pin 18 on the PS-->MB cable) was +0.79V.  This is
a bad sign.  What hints are there?
