Mac Mini Late 2012 Dual Hard Drive Kit
Great guide, I would that this antenna fix also applies to the W201 (1984 190e) model as well. Also, if the small gear is worn (like mine was) it can be fixed by removing the old gear with a Dremel tool and using a #14 gear which can be found at Hobby Shop specializing in Radio controlled cars and planes.
I was able to order the frame and digitizer as a unit which greatly helped in the repair for a cracked screen. Much easier to fix than iPhones with a cracked screen. It took me less than 30 minutes.
Another device fixed due to iFixit. One iPhone 4, 1 MacMini, 1 MacBook Pro and now an iMac! You guys are better than awesome!!!
