Those who want to take a look at the innards of the new iMac, but don’t want to spend the moolah, can take solace as iFixIt has done a piece by piece teardown of the new desktops. The teardown reveals that the Display is manufactured by LG and that its sports an Intel L102IA84 EFL Thunderbolt port IC.


But the most interesting bit among the other revelations was that the GPU board is now detachable. iFixIt states that "With a bit of magic, the GPU heat sink detaches from the logic board, exposing the AMD GPU board". That means buyers need not replace the entire logic board if the GPU in their iMacs fail.  The website also discovered that the iMacs use Hynix GDDR SDRAM chips for the AMD Raedeon 6750M/6770M/6970M (depending on the model purchased) and the HDD used on the iMac used for the teardown was the Western Digital Caviar Blue.
