The iMac Core i7 4.0 with 27-inch screen is a built-to-order iteration of the iMac Core i5 / 3.2 27-Inch (Retina, 4K, Late 2015/ Skylake) or the iMac Core i5 / 3.3 27-Inch (Retina, 4K, Late 2015/ Skylake) 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 iMac Core i7 4.0 27-inch (Retina, 5K, late 2015) features a quad core 3.2GHz Intel Core i7 I7- 6700K processor (Skylake), with four independent processor cores on a single chip, DMI system bus and an integrated graphics core, 8 GB of RAM, a 1 TB or a 2 TB Fusion Drive, an SD memory slot card reader, an AMD Radeon R9 M390 / M395 graphics with 2 GB of shared memory, a built-in FaceTime HD webcam and stereo speakers, as well as two “Thunderbolt-2” ports and 4 USB 3.0 ports. It also has built-in AirPort Extreme (802.11g) and Bluetooth 4.0. 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. The iMac Core i7 4.0 27-inch (Retina, 5K, late 2015) is shipped with a compact aluminum Apple Wireless Keyboard and either with a “Magic Mouse -2” or a traditional wired Apple Mouse or a multi-touch Magic Trackpad. Upgrade from “Magic Mouse -2” to a Magic Trackpad-2 is optional for an extra cost.
