It should be a half hour work, but it took me
much much much longer because of a stripped screw, which caused the optical bay cannot be taken out. Tried many ways, and finally got the screw out by soldering a small and cheap flat-blade screwdriver to it. A video can be found in youtube.
- Be very careful not to spatter solder to the Mac logical board. It's better to cover it with something
- Use a larger and sharp flat blade screwdriver to clean the surface of the stripped screw
- If it doesn't work for the first time, clean the surface and try again.
