Atom MB (very small) with 12v power can be had for ~$100 (I have seen them 
as low as $69) And run anything any other intel chip will run. They do 
have a 16bit audio out/in, though latency on jack is at best 64/3 (my wife 
has one in her desktop. Video chipset is not real useful for gaming or 
videos, but fine for desktop use (and not relevent for headless). There 
are serial ports, so there is a possibility of having native MIDI porting 
with a little HW/SW glue. Some of these do not have the 12v input but will 
run from 12v with a very small adaptor. An old laptop ps could fit in the 
box meaning no lump in the power cord.

Some of them also have a par port... which could be used for switches on 
the box... but it would be easier to pull the board from a cheap ($3 or 
so) keyboard and wire switches to that.
