For anyone here with an interest in any of these domains, I'm happy to
offer free hosting for at least as long as I'm alive (working on finding
volunteers to take care of things after that). I've hosted some of my
accounts and sites since the '90s and can provide email, web, dynamic web,
development, gopher, mailman and more.
I have real colocated servers, not purchased services, and the servers
are, if nothing else, interesting. The collection include an AlphaServer
DS25, a Sun Fire v254, an AMD Ryzen box (with ECC), a 1U Amiga 1200, and a
1U VAX.

What OS do you run on the Amiga 1200 that is in a 1u case?
That is pretty odd :-)

I would assume it can run Linux/Unix stuff? Though not sure you could get
an accelerator on it.
I wonder if it was some solution sold to TV stations that used an Amiga
and a genlock in a box?

The Amiga 1200 and accelerators for it are a form factor of a slightly thick and deep
keyboard. Therefore, accelerators are made which don't require much height. The
motherboard and accelerator fit tidily in a 1U case:

BTW - the pictures there are from the days of film cameras - that's how long ago I
put it in that 1U. After recapping it a few years ago, it's back to being 100% stable.
Given that there are plenty of new film camera available for sale, I?m not going to hazard
a guess as how long ago that was. The photo?s I took last weekend were on 35mm film.

a box? All the machines run NetBSD, and the Alpha, UltraSPARC
and Amiga systems compile pkgsrc bulk binary packages for each of their architectures.
While I do use the 1U VAX to do test compiles, with 24 megs and 5 VUPs it wouldn't
make much of a bulk builder. I have a VAXstation 4000/60 and a 4000/90a for bulk building.
Okay, I was wondering if this were how you?re using it. This was just about the only use
case I could think of for a rack mounted A1200. Have you considered virtualizing your
build servers?
Speaking of VAXstations - can anyone recommend someone
who does power supply recapping and repair? I would like to get the power supply of the
VAXstation 4000/90a fixed, and while I could just open it up and replace the whole circuit
board with one from a modern power supply, I'd really rather keep it at least somewhat
original.
That?s a good question, I have four VAXstation 4000?s, the one /60 runs 24x7, the other
/60, as well as the /90 and the /VLC need work. I know the VLC has power supply issues,
though if I remember correctly they?re with the bearings. I don?t remember what?s wrong
with the other /60, and the /90. I don?t think I?ve ever had the /90 working.
I?d love to get one of the ones that isn?t running turned back into a workstation.

There are three issues with that:
One, I don't really trust x86, considering the Intel Management Engine and
AMD PSP aren't openly documented, so I prefer to run important services on
non-x86.
Two, emulation isn't perfect and there are occasionally edge cases which
occur because of things that are ever so slightly off because of FPU
accuracy or things like that.
Three, emulation is often not as fast as real hardware. A VAXstation
4000/90a is about as fast as SIMH running VAX on a really fast x86, and
m68k emulation is often slower than on a real m68060 because BSD requires
an MMU, and that means that JIT can't be used.
That?s a good question, I have four VAXstation 4000?s,
the one /60
runs 24x7, the other /60, as well as the /90 and the /VLC need work. I
