Took years of searching and all it required was a popular r/hardwareswap post but I got this last year. Very unique machine in my collection. It runs OpenBSD and some Linux distros (with a bit of hacking.)
Willing to go into more depth if people are interested.

      It can probably run DOOM, but the gpu is pretty paltry and you’d need the Crysis source to recompile to MIPS.
