Instead of purchasing a new or reconditioned iPhone Scotty from Strange Parts decided to build his own. If he was in any other country this would have been near impossible but he was in China. There are lots of repair and recycling facilities that were able to sell him the bits and pieces that he needed. At 6:15 you can see Scotty purchase the display and digitizer from a repair facility. The parts used are probably not genuine Apple parts but rather the common aftermarket parts that are used to repair the phones if they get damaged and are repaired by a 3rd party vendor. The small shop has some impressive machines including a vacuum chamber that I am thinking a local repair shop would not have. The iPhone logic board is the main control board of the phone and since this is a phone the components are extremely small. He was thinking of purchasing a bare logic PCB and then purchase all of components separately. This would be a crazy undertaking. I think he went the better route which was to purchase a repaired one. With a huge bag of screws in hand and a ton of tiny parts he actually completed the build and now has a working iPhone!
