I just won a 733Mhz QuickSilver that I (eventually) hope to install into a Digital Audio. Probably not that great compred with the 733Mhz DA CPU but it should still make a nice upgrade from a 350Mhz G3. I plan on putting an 80GB HDD, a flashed FX5500 (for Core Image) and a DVD-RW in it. SHould be a nice workhorse when it's finished
