The 4301A model only has one of these antenna arrays. There is still a spot for the second one on the corner, where the fan is so I’m guessing they might’ve integrated one of these antennas into the board somehow on this model.

And don’t forget about the two torque screws next to the laser lens before you remove the top of the system. Otherwise, the laser unit will be mounted to the cover that you’re trying to lift up.

These two parts slide off. Towards the hard drive side of the unit do not pry them off. You will break the tabs.

I did the exact same thing. Super easy popped right off.

I see that it was attached to the plastic shell in yours. Mine was not it was clipped into the drive.

You forgot to mention the metal piece that you have to remove before you hit the 6 screws

mine had 11.
