Sparc:
I'd recommend a Sparcstation IPX; small, and can be run from a serial
console. Cheap or free; it maxes at 64MB RAM. You can run Linux on it.
I have two running Solaris 2.6 .

Never had much particularly bulky stuff; I had to leave the hp 9000/370,
9000/433s, their monitors (about 200lb total), the uVaxII and other stuff
behind when I left the U.S. I kept the hp 9000/380, though, and it is
up as nazas.autonoma.edu.co .

The HP3421 is even bigger.

Hmmm... I'd recommend a Decstation 2000 for the R2000. Though I am not
sure about the status of free OS's for it... I am not sure if netBSD
supports it... there was something odd about the way it handles pages.
But I remember using a 12MHz model with a mono framebuffer;
Ultrix; interesting for its time. It made a good ftp server until about
three years ago, when we decommissioned it. I think Linc Fessenden
ended up with it. Are you still there, Linc?
