Yes, I would never want to go through with all that Dave suggests - and

expense and environmental consequences of constantly running fans, but
to get back to my unanswered question:

Assuming CPU shutdown is to happen after more or less daily use of a few
hours at most, does daily 5v "soft power" re-energizing of motherboard
via power supply rocker switch prior to reboot add significant, or even
measurable wear and tear on its circuitry?

OK, ~misfit~ just answered this while I was posting the question, so I
will leave the switch on permanently to avoid the strain of on/off
switching on the power supply itself . . . unless of course someone has a
more compelling argument favoring the alternative approach.

Thanks, Nick
