What a system!

The other answers were valuable and I'm going to reply to them later,

So now the expert on Newsgroup posting has taken to replying to his own
posts? Wonderful. Take bit of your own "expert" advice and start
trimming your posts. We really don't need to read the entire thread
over and over. Nor, for that matter, do we need to know the saga of
your missing wallet and who, exactly found it and where.

Somehow I don't think your idea of drilling 1/2" or 1" holes in the case
of your UPS for added ventilation is the brightest idea. To ensure you
don't accidentally damage something and not have a working UPS when you
need it, I'd suggest drilling those holes while the unit is plugged in.
That way you'll know immediately if you damaged something.
