Thanks, Tim. That thread was very helpful. Seems like there were
two problems discussed: Cases built in 1998 and before with EMC
filters that occassionaly melt after 5 years of service or so. This
was the problem that started the thread. Then there was at least
one person who had a transformer melt, and the explanation was that
it was just a dodgy transformer.

My problem is more like the second one, since I have no EMC filter
and the gooey stuff came out of the transformer itself. The power
supply is only about 8 months old. I wonder how long the warranty
is. Probably doesn't matter, since I have probably voided it
anyway. M biggest concern is that it doesn't happen again.
