I'm pretty sure my 9800 Pro can be dropped down to 8-bit color. The single processor will help while running 9. When my old MDD had the dual 1 GHz processor module in it, if I ran 9.2.2, the fans were full-speed. After I swapped to the single 1 GHz module, it became bearable. Granted, mine had the early 400 watt power supply with the noisier fans. It won't be as quiet as a Digital Audio, but shouldn't be too bad, as long as the computer is under the desk.

Anyway, nice score.

Personally, I'd go ahead and have a partition with 10.4.11 or 10.5.8 on there, just for those times when you may need to use it as a backup machine to go online, etc. But, that's just me.
