Refurbishing a PlayStation 4

I picked up this 500GB black PlayStation 4 console and controller from an estate sale just a couple miles away from my house. It was in great condition except for the fact that it wouldn’t eject discs, and the warranty sticker had been removed, meaning somebody had unsuccessfully attempted to repair it. Surprisingly, the issue was just the fact that it was dirty! There was some gunk on the connection for the eject sensor that I was able to clean off with isopropyl alcohol. I took the entire console apart to individually clean each piece, fitted it with some new thermal paste, replaced the ribbon cable that I accidentally broke the tabs off of (my bad!), and gave it a nice polish.
