A top metal plate, power cable, and three delicate looking cables guard the entrance to the cave hard drive bay.

The power cable with socket attached lifts away easily.

Removing four T8 Torx screws releases the plate. Use a T8 screwdriver, as it is difficult to gain purchase on the screws with an L-key and risks rounding them.

Once the four screws are removed, the metal plate simply lifts away.
