This guide gets you 90% of the way there. Some really important pieces are missing though, primarily:

- How you dont need to unplug the power supply cable from the motherboard, you can just unhook it from the plastic clips on the case.

- It never mentions cleaning the old Thermal Paste off the heatsink + cpu and replacing with a new dab.

Both of these are essential for a proper tear-down. If you dont replace the thermal paste, your PS4 is guaranteed to break down irreparably in the future. I had to know or discover them for myself. Please, please update this guide with that info.
