IMac (Intel-based)
The iMac is a series of Macintosh desktop computers offered by Apple Inc. The current Apple iMac features either an Intel Core i5 or Core i7 processor, Nvidia GeForce 600 series graphics cards, and a choice of either a 21.5" or 27" LED-LCD display.
Previous iMac models featured either a white polycarbonate enclosure or an aluminium enclosure. The 2009 iMac model featured a unibody aluminimum enclosure, which can still be seen on the current model. The current iMacs released in October 2012 also feature a much thinner display, with the edge measuring just 5mm.
