I managed to snag the chassis and what I hope is the matching cover. I thought
it looked like an 8/e or 8/f.
When I bought my PDP 8/m, I also picked up 2 extra complete board sets
(including front panels, and power supplies from the seller's swap/repair
stock. The front panels are the 8/f/m versions (with LEDs), as are the
switching supplies. I've been looking for a chassis ever since, although I
suppose I could have adapted a commercial 19" chassis. Now I need to find a
backplane (or 2), bezel, and lock.
As a side note, I bought my 8/m from a guy who ran a business setting up
leather and textile embroidery (cowboy boots, etc.) systems based on DEC PDP/8
and PDP/11 controllers. The business was still going as of 3 years ago. The
owner was working on a EPROM emulator to simplify programming of a particular
PDP-11 based controller, which stored the designs in EPROM. He apparently
still had some customers running setups in Canada and India based on 8/a
systems. He was just getting around to retiring the last of the 8/m based
systems. His shop was (hopefully is) a living vintage DEC museum, but for him
it was simply his work. Of course a Raspberry Pi could fully replace those
systems, even running the PDP-11 embroidery design software on SIMH, but
apparently customers don't like to mess with working systems.

It's an 8/e (of which I have two, and a nearby friend has three or four
more, as well as a couple of 8/Ms) chassis. It takes a big linear PSU
and two 10-slot Omnibus backplanes. The 8/F and 8/M (OEM version,
usually with a very simple turnkey panel) are shorter, take only one
10-slot Omnibus backplane, and have a completely different switch-mode PSU.
