It just needs to be open source software, open source
hardware, also
 available assembled, optionally bundled with or mounted in floppy
 drives for 3.5" 5.25", 8".
 It should sell for less than $20 (with 3.5" drive, slightly higher with
 8", even higher with multi-drive 3",3.25",3.5",5.25",8" in
a single
 cabinet)
 Support should be live 24/7. 
Fred,
You had me at 24/7. Put me down for two!
