This video is about installing second serial ATA drive into a Power Mac G5 system. The video is a step by step demo starting with the removing of the door to the machine and the air pack. The first hard drive is at the top rack and you have to remove the four screws at the bottom and insert them into the top and bottom screw alls on each side of the drive. The hard drive is inserted below the first hard drive and the data and power cables are plugged into their respective slots. The video is highly useful for those who want to install the hard drive on their own without a hardware technician.
