Step 16
If your new optical drive already has a bracket and bezel for your model, then you are done.
Remove the 2 Phillips screws from the side with the longer bumper.
Remove the bracket from the optical drive.
Step 17
Remove the 2 Phillips screws from the other side of the optical drive.
Remove the bracket from the optical drive.
Step 18
Depending on the new drive's model, the bezel on your old drive may not transfer to the new one. The bezel is not strictly necessary, and the drive will probably work fine without it, but you should transfer it if you can in order to ensure proper alignment with the case.
Remove the 4 Phillips #00 screws from the top of the optical drive.
