I've still got a couple small business models along these lines that are over 20 years old now. Still running possibly because I always turn them fully off when not using them. No hibernation, sleep or other monkey business.
One Dell has an early 64-bit mainboard but only a 32-bit CPU in that socket, just fine for Windows XP and will also run W10 32-bit (slowly), mainly dual booting to Debian i386 now since it retired from office work. Puts out so much heat I would imagine there is a lot of bypassed silicon on the chip drawing power but not helping process. IIRC a 64-bit CPU for that socket was known to exist but was more or less "unobtanium".
Then a trusty HP tower with the Pentium D, which was supposedly a "double" with two x86 arch patterns on the same chip. This one runs everything x86 or AMD64, up until W11 24H2 where the roadblocks are unsurmountable.
