Released in October 2009, the new iMac joins the family of “Unibody” designed Mac’s. This follows the trend of the already popular Macbook Pro Unibody Aluminium design. The iMac is surrounded by aluminium back to front with a full aluminium stand to support it. There are only 2 removable parts on the iMac, the first is the bottom plate for RAM upgrades (much like the previous generation) and the front glass which gives you access to the iMac’s hardware. However removing the glass and any hardware is not recommended and will void any warranty on the unit, but does give the user the possibility of upgrading the hard drive.


The screen size of the iMac has been upsized. The iMac comes with a 21.5-inch LED backlit screen with 1920 x 1080 resolution and a 27-inch LED backlit screen with 2560 x 1440 resolution.
