Self hosting on retro computer?

I'm big on retro tech (which, sadly, is becoming code for credit bills in a trenchcoat; why did I give all that good shit away :( ) and occasionally think "damn, I should try to get an old C64 or Amiga, specc it up and use it as a daily driver".

Then I got to wondering "do folks still use retro PCs to self host cool stuff?"

So, do folks here still use retro computers for self-hosting- either actually hosting services on the old hardware, or self-hosting lightweight tools specifically for use from vintage machines?
