i have an 2011 27" imac and i set up an old sony high fi stereo to it, but my desk is quite small and the speakers have to RIGHT next to it. i know that with the led/lcd screen its a non issue. but what about the hdd and other components inside of the computer.i was thinking that since its a unibody aluminum design it would be naturally shielded, but i would like some more insight, i will add pictures.
