Adding an Internal IDE Hard Drive to a G5
I decided to mount the drive on the shelf immediately above the Processor Bay. This meant that I had to fit the drive with the connectors facing the PCI Bay Fan. To make a long story short, I attached three neoprene feet to the drive caddy which gives it some room underneath. I removed the CPU fans, PCI fan, memory, Airport Card, and Optical Drive and then hand drilled a small hole in the shelf using masking tape and a vacuum to ensure no metal fibres got into the electronics. This hole was for the tab in the front of the caddy which faces the PCI fan. The screw goes thru the neoprene foot and is secured by locking hardware to the shelf. I also removed the PCI card guide as I don't intend to install any Super Long PCI cards---the PCI Card Guide would interfere with the caddy and must be removed for this particular mod. I then installed the Caddy with HD and reinstalled all the parts and cables I removed including the sensor wire. I installed the PCI Tempo Card cabled the Drive up and Voila! I now have the HD working just fine in addition to the SATA's.
