I had a FreeBSD doitall-machine from 1998 to 2006 on some Pentium-ish thing with an AT motherboard. Moved a few thousand miles and it didn't get unboxed, until 2020 when I needed an AT PSU for something unrelated. Prior to cannibalizing it I powered it up long enough to check that it would still send email and run brief X session to hit YTMND in 15 year old Firefox.
