Not sure if this has been listed.
PRO TIPS from a non-pro:
1 - Keep screws separated and labeled by step # and size.
2 - Be very careful to get screws in properly threaded, its VERY easy to strip the ccrew holes and screws. Especially the case. Not that it happened to me…
3 - It was impossible for me to get all the adhesive off the case from under battery, it left a lot on w/o issue (yet).
4 - Make sure you have Aluminium Foil before starting!
5 - Upgrade the SSD or HDD while your in there!
