Are sawtooth motherboards with rev 7 chip common and > cheap? Will a newer motherboard (GiGE?) fit and work with the old PS? I feel your pain as I am in the same situation with my Sawtooth. There are supposedly two versions of the Sawtooth motherboard 820-1093-A (v1) and 820-1094-A (v2). I've been meaning to check and see if mine is the v1 and, if so, try and find a cheap v2 board. Changing motherboards completely will probably mean a different PS (to provide the ADC's 28 volts) and a different back panel (rearranged ports). I'd say that unless the v1->v2 swap works, then your best bet is a fast single.
