The PSU will be mounted above the optical drives.which is as far as I can tell the only place a regular size ATX PSU will fit in that case. I picked up a 500W Cooler Master PSU that has a nice 120mm fan and an open grill at the back that should allow for good ventilation inside the case. It's nicer looking than my old stand-by, black tape, and makes a stronger connection. I used heat-shrink tubing to cover the solder joints. The wiring loom has been cut from the old power supply, and is ready for soldering. I'd considered cutting the ATX connector off the new PSU and soldering wire to loom from the MDD PSU, but thought this would be a bit cleaner and gives me the option of salvaging the new PSU if something goes wrong. This is the ATX extension I'll be using for the connector. There's nothing visibly wrong that might have been an easy fix, and the PSU is pretty densely packed and has a lot of silicon caulk applied to keep components from shifting. Tried replacing it, but the new fuse blew as soon as it was connected to the mains. When I opened it up, I found the fuse was blown. (thumbnails are clickable for larger image) There isn't too much out there on mirror-door to ATX conversions, despite their flaky power supplies, so if there's some interest, I'll snap some photos while I'm doing the wiring and installing.įrom what limited info I've found on the MDD conversion, the 28V is only necessary if you're going to use the ADC conector, and probably firewire. I picked up a better PSU, with a rating closer to that of the original, and wanted to know if there was any interest in having the process documented. It is in fully working order and is currently running Mac OS X 10.2.3.I've just picked up a mirror-door G4 for cheap, sold as a 'won't power on' unit.Īfter a quick test, and it does power up with a re-wired ATX power supply.

When I acquired the unit, I completely disassembled both the tower itself and the keyboard for a thorough cleaning to remove dust and debris that had accumulated inside. It also sold at a much lower price of $1299, compared to $3299 for a G5 at the time.

It is similar in configuration to the Summer 2002 dual-1.25 GHz model, but has only a single processor, a smaller hard drive, less RAM (from the factory), and a ‘combo’ CD-RW / DVD-R drive instead of a SuperDrive. It is notable for being the latest machine ever made by Apple that could do so. This particular machine is the Mirrored Drive Doors (MDD) 2003 model, released in June ‘03 alongside the first Power Mac G5s, since there were many users who still needed to boot Mac OS 9. It’s complete with the original packaging, foam bag, power cable, keyboard, mouse, modem cable, VGA-to-DVI adapter, software CDs, and documentation.
