As usual, iFixit has posted its incredibly detailed and in-depth teardown of Apple's new late 2012 iMac. Aside from all the guts and glory, it appears that Apple is now assembling the new 21.5-inch iMac in the USA as the little laser etched string of credit tells us. But why? We're not sure yet. What we do know is that this isn't the first time Apple has assembled iMacs and other products here in the USA, but those were typically assembled in the states due to being either made-to-order or refurbished units.
