just an update havent had too much time to look into the power supply further.  But one thing, i did stumble across a site called atxg4.  He has adapters to use atx ps in g4's. He has the one i need specifically for the mdd.  Also he has another i could use for a g4 i picked up for myself a few yrs ago for 3$ at a garage sale.  He has the one for the gigabit g4.  Does anyone have experience with these adapters? I understand that the adc would be gone, well that monitor that gets its power from the video port, as well as sleep issues.  These wouldnt be a problem as  i dont have one of those monitors as well as the g4 mdd im wrking on for someone, doesnt have that monitor either.  I am leaning towards these options, as if i try to recap and fix the ps on the mdd, im thinking it might have stressed other components on the ps as well and may lead to other problems down the road.  At least this way that person and i could both just use standard atx ps's on it.

  Finally, on that site the guy can only accepts orders via etsy?  I've never heard of them before, so has anyone ever ordered from him via that site?

Thanks.
