"Michael A. Terrell" hath wroth:

Have you EVER seen any instrumentation cards for a MAC? I've seen
ISA, EISA, PCI and the pc-104 industrial variant os the EISA buss.

Add EPIC, EPIC Express, ITX, Mini-ITX, Nano-ITX, EBX, PCI-104, PC-104
Plus, CompactPCI, EPIC, EPIC-Express, PC/104, PC/104-Plus,
PC/104-Express, PICMG, AMC, ETX, ECX, XTX, COM-Express, COM-Express,
and probably a few I've missed. PC's own the industrial control
market. The catch is that most boards are rather expensive.

See:

On the right side is a list of "projects" that various users have
built. They range from ingenious to ludicrous. All are interesting.
I suppose that could be done with a disembowled Mac, but Apple doesn't
sell motherboards so it requires cannibalization of a complete
machine. So much for the hobbyist market.
