During Apple’s transition from PowerPC to Intel Processors, the aesthetic design of Mac computers have also begun to transition from white polycarbonate plastic to an all new aluminium shell. The new iMac, alongside the Macbook Pro, Mac Pro and Mac Mini has joined Apple’s lineup of aluminium bodied computers.

The back plate of the Aluminium iMac can no longer be removed, this limits the consumers access to the hardware. The RAM however, can still be easily upgraded by removing a small plate on the base of the iMac, giving you access to add and remove memory.


The aluminium iMac comes in 2 models, the 20-inch with 1680 x 1050 resolution and the 24-inch with 1920 x 1200 resolution. All aluminium iMac’s were powered by an Intel Core 2 Duo Processor ranging from 2.0GHz to 2.93GHz, ATI Radeon HD Series & nVidia GeForce Series graphics, Mac OS X 10.4 “Tiger”, OS X 10.5 “Leopard” and OS X 10.6 “Snow Leopard” operating systems.


The aluminium iMac was discontinued in October 2009, making for an all new ‘Unibody” design of iMac’s.
