Yes you probably wouldn't need to go that old. As I recall Pentium 4 motherboards of the generation around p4 "northwood" and "prescott" still had floppy drive headers commonly built into them. Probably there's some motherboards that have FDD headers and are also new enough to run an AMD64/x86-64 understanding CPU to run a current linux kernel without having to hunt down i386-everything for the operating system install.
