It seems to me that a large percentage of original PCs, XTs and ATs that I've ever
seen have been missing the plastic rear trim panels. Is there any particular reason why
those seem to have been so commonly removed and lost or discarded?

I didn't even know there was supposed to be a rear trim panel!! Shows how
common they were, I guess ;)

5150 did not have any sort of plastic rear trim panel.
prob'ly the later ("Post-PC") PC/AT 5170
and, few of those still had them by the time any of us saw the machine.

I've only ever seen ONE and it was on a PC/AT.

I got my 5150 new in 1983 and I don't know what you mean.
Maybe it was only on later versions?

I think a comparable product stream was the IBM "Options" for the PS/1
era systems, consisting of monitor power savers, etc.

Do you know whether the 5170 always came with its rear trim panel, or it was an optional
accessory for installations where the AT would be on a non-wall-facing desk?

To the best of my recollection, the 5170 in its native form did not
include a trim panel. However, it was included (ISTR anyway) with the
"sit the box vertically on the floor" IBM kit.

I don't think I recall seeing that 5170 configuration before. I'll try to google
up some pictures to see if they shake out any old memories.

That was option 0218 for the 5170.
Looking at the 5170 "Installation and Setup" guide, it does mention the
back panel. The 5170 that I owned didn't have it. It seems to be stuck
on with adhesive strips. Perhaps at some point, IBM quit shipping the
5170 with it.

This page has pictures both with and without the trim panel:

On my AT, the plastic panel's held on with self-adhesive velcro
strips. By the time I got it in the late 90s, the velcro was just
barely hanging on -- so by now, I'd expect most ATs to need some
assistance retaining their panels...
(I don't know if the velcro was original, or a replacement for something
that was even less effective!)

My 5170 came with a plastic panel still in its sealed
transparent bag. It has four velcro straps glued on with the
mating side with adhesive tape with peel off paper protection.
So it was original.

So, there wasn't any such thing INSTALLED. It's still in a sealed
transparent bag, in the box, with the rest of the packing materials.
I saw one, on a 5170 that had a gold, instead of silver, front badge.

New subject: IBM PC rear trim panels�^@� Why are they uncommon
The 5150 also had covers for unused drive bays, and filler brackets for
unused slots. Both of those are pretty common.
The TRS80 had a cover for each cable port. The only one of those that is
commonly still around is the one for the RS232 port. In FPUIB last
year, I had had a handful of those unused, still in the plastic bags.
There was also a cover that went over each port WITH a cable.

Actually, it awas _2_ covers. for each conencotr. One if you didn't use
it, one if you connected a cable there.
On the keyboard/CPU unit there was a little lift-up flap as standed. If
you conencted the EI, you ftted a different cover aorudn the cable ddge
conenctor, which jsut pushed on.
On the EI there were flat plates with ridges on the inside to fit onto
card deges thte were not used. And hoods to fit round the edge conenctors
on cables fo ones you did use.
Actually, I don't think they suppleid a blanking cover for the CPU cable
conencotr on the EI, since that _had_ to be used. So just the cable hood
there.

I think I used all the cagles on my EI. If there was one I didn;'t use it
would ahve been the paralell printer port.
