Hey, I just bought an iMac G5 off of eBay. The specs are as followed: iMac G5 17" [no iSight] 1.8GHz PowerPC processor 256MB RAM 80GB HD SuperDrive I want to know if the 2GB RAM in my Dell XPS 410 will work in the iMac. From pictures I've seen, the sticks look the same. Also, does this iMac have the ambient light sensor? Help is appreciated!
