found a pretty complete manual
here
fixed the fan problem with a bodged - er i mean modded - molex/fan extension cable.
also improved the PSU situation by using the spliced wiring from
here which seems to make things more spec-compliant than just cutting the cables.
also noticed that the caps-lock key on the USB keyboard flashes when it's powered up.
have tried 3 different AGP monitors with no joy. also tried all the different reset procedures, like popping the battery out for 10 mins etc.
stoopid question: will any AGP card work or do they have to be special Mac-compliant/certified ones?
Thnx again
