Here's the latest on the Cube that I burned up trying to tap into the 5v supply for a fan: The DC/DC board had obvious burn damage, as did (2) 512MB RAM Dimms. After replacing those I was still getting nowhere; an authorized service center suggested the motherboard was bad, but could not go any further because the supervisor informed the tech that they did not repair Cubes - must send to Apple. I purchased a new motherboard and chassis for $224 from DealExpress, received today and swapped out everything. I reassembled, installing a new (blank) Seagate Barracuda V 120GB in the process. I now get the power to stay on, and I hear the video card fan going, but no CHIMES, and the CD drive (with an OS 10.2 install CD) fires up for a moment, then stops. Nothing else happens, and I am at my wits end. At this point I have spent $180 for a DC/DC card (with trade, from Small Dog), $240 w/shipping for the motherboard, still have to replace a Gig of RAM, and I am not back up and running. I MISS MY CUBE w/CINEMA SCREEN RUNNING, and there is little left to replace on this thing except for the processor/daughtercard. Any suggestions and/or anyone qualified enough to look at this thing without spending much more?
