Type All-in-one
Processor IBM PowerPC G5 2.1 GHz (iMac iSight)
Memory 512 MB – 2.5 GB
Storage 250 GB – 500 GB

Weight 10 kg What reviewers say Reviewers praise the clean all-in-one design, bright display and responsive everyday and creative work. The camera and remote add useful features, but both find Front Row rough around the edges; Macworld also highlights restricted upgrades and VGA-only external mirroring.
