It was a cheap power supply in an otherwise just right case. The 250W
supply works just fine. So that seems to rule out the Chinese as the
source of the problem.

The usage was under 50% on the first power supply. Now it is near 25%.

Antec did not then, nor even now, makes any case that meets the requirements
I had at the time I built the machines in question. Today I have different
requirements and alas, an Antec case does indeed fit just right. I have
two of them here, now, ready for stuff to be installed (when parts on the
critical work path finally arrive). Unfortunately no one supplier carries
everything I need. I've ordered from 4 different places so far. If I
could get it all from Newegg, I would, as they have been fastest and doing
the processing and delivery. But they do not carry 100% of models and they
do run out of things sometimes.

Because YOU say so? I do quite well figuring out what I need.
Actually I would, if they would ever figure out how to design a web site
properly.
