I wouldn't. Go to the Computer forum here and see what I posted there on using an $800 P-4 computer for this purpose. Since the Shuttle has on-board 5.1 audio, if your primary app was simulating a Tape Deck (with all of the advantages of non-linear editing), you could use a Dakota board from Frontier Design Group (apx. $400, and Audition from Adobe (used to be Cool Edit Pro, apx, $200). This would give you 16 independent channels of 24-bit audio I/O, a complete control interface, and with the Dakota card, you get synch, 2 MIDI ports, and access to the best support people in the business. BTW, in the day, I also had an 80-8, and a 40-4, and a 3340, etc.
