NetBSD is probably what would make most sense to run on that old hardware.

Alternatively you may have accidently built a great machine for installing FreeDOS to run old DOS games/applications. It does install from USB, but needs BIOS so can't run it on modern PC hardware.

NetBSD is the only 32bit modern Unix still running like a charm on 32 bit hardware. OpemBSD is second with great wifi support.
