I have just acquired a 12" iBook G4 1ghz with combo drive, 512mb ram, airport extreme, and 30GB HD that's loaded. The problem is that the previous owner spilled water on the unit, rendering the logic board kaput! Apple wants $690 to replace the board and the cheapest I've found a board online is $600. I could do the repair if I could find a board cheap enough. Does anyone know where I could find one cheap? This thing is in mint condition aside from the board and I'd really like to get it working. Thanks!
