A large-screen Apple iMac 27" in the classic aluminum and black-glass design, model A1312, EMC 2390 (Mid 2010). The big widescreen display makes it a comfortable all-in-one for home office work, photo editing or everyday browsing, and it suits anyone who wants a roomy Mac setup with just one cable to the wall. Around the back you'll find four USB ports, FireWire 800, Gigabit Ethernet, headphone and audio-in jacks, and a Mini DisplayPort, which on this generation also supports Target Display Mode for using the iMac as an external monitor.
