iMac (27-inch Retina 5K, 4.0GHz Core i7, Late 2015)

The iMac (27-inch Retina 5K, 4.0GHz Intel Core i7, Late 2015) is a built-to-order iteration of the iMac (27-inch Retina 5K, 3.2GHz Intel Core i5, Late 2015) or the iMac (27-inch Retina 5K, 3.3GHz Intel Core i5, Late 2015) but with the top-class Core-i7 Skylake processor designed for overclocking. The desktop exterior design is similar to the iMacs of 2012. This is the all-in-one desktop computer in an ultra-thin (5 mm depth at the edges) all-aluminum unibody casing behind the 27” LED-backlit IPS widescreen Retina 5K display. There’s a bulge though in the center of the back panel to house all the hardware. The computer is mounted on an aluminum stand with a slightly tapered foot and an adjusting hinge.

The cooling system is CPU controlled and the in-built speakers are mounted beneath the 27-inch screen for the clearer less distorted sound to bounce off the desk or other surface. The speakers’ grills also work as the vent ones.
