Rating: 4/5 A Bargain Upgrade to MacOS November 15, 2016 My Mac mini from 2009 can't be upgraded to MacOS so I moved my files to this iMac. Considering that most iMac configurations, even refurbished ones, can run from $1000-1500, I took a shot at this $649 bargain. With a small 250GB HD, I added a 1TB Firewire 800 external drive to handle the Home folder and all of its music and photos. So far so good!

Rating: 5/5 Very helpful replacement January 18, 2016 Needed a replacement for an older iMac at work office. Primarily needed for email and Web surfing; this product fulfilled our needs at considerable savings over a new unit (and still has DVD slot). Essentially no external signs of use.
