[power cycles and effect on computers]

What's your contention based on?
It's based on mixed results of studies from companies like HP, Dell &
Compaq over the years, described several years ago in either PC
Magazine or PC World - I don't recall which. They said that
obviously, you shouldn't turn it off & on every time you get up to
use the bathroom, but on in the morning and off at the end of the
day? No extra wear they could point to.
Studies I read in days past seemed to indicate the other way, that the
heat swings of power cycles stressed the boards and components. It also
went along with my personal experience of the various workstations and
PCs we had in the labs, I tended to see fewer problems with the 24/7
machines.

bear out these ideas. There are 3 machines here, all with hard disks
over 8 years old. One runs day & night as a server. The other two are
shut down at night. No failures for any of them.
I haven't seen anything from you that changes my mind. That's the cool
thing, I only said that I "firmly believe" that it's true. It would
take compelling evidence to change that.

other piece of electrical equipment in the house, like TV, stereo,
etc.
None of those are personal computers.
So? Except for the hard disk, a computer contains nothing so
different from a TV, VCR, DVD player, etc.
In point of fact, I don't turn off the VCR (unless I need to record) or
the DVD player. The TV, like a monitor, is a big power draw item, and
has high reliability compared to the other items mentioned.
