Hugh Jeffreys bought a wrecked MacBook Pro for $100. The hinge was broken, the case was bent, dented, and scratched, and two of the bottom feet had fallen off which allowed the inside to become filled with dirt.
He started by opening it. It was filthy inside. He cleaned out the fan then powered it up. Fortunately, it booted and the display seemed to be in good working order.
He bought a replacement battery, a new bottom case, upper case, top lid, front panel glass, a 500 GB SSD, and a new clutch cover. The video shows how he removed all the broken parts and replaced the new ones. It looks like a lot of work but the end result is great. And now he has one of the good kind of MacBook Pros, not the bad kind with the USB C port.
