| The case is divided into two halves, a top and bottom-case, as well as the internal assembly. The top-case is secured by a single screw positioned at the back. | The case is divided into two halves, a top and bottom-case, as well as the internal assembly. The top-case is held in place by plastic clips that run around the periphery and is further secured by a single screw positioned at the rear. The front of the PCB and switchplate assembly is held in place by a rubberized gasket that runs along the length of the keyboard and also serves as its front foot. The rear of the switchplate is held in place by two plastic clips that extend from the bottom-case. The two ADB ports (mini DIN-4) at the rear are on individual daughterboards that connect to the main PCB with short ribbon cables. |

| The keycaps are made primarily from PBT plastic except for the spacebar, which was made in ABS plastic. They boast a unique profile exclusive to Apple keyboards of that era, such as the [[Apple Standard Keyboard]] and [[Apple Extended Keyboard]]. | The keycaps are made primarily from PBT plastic except for the spacebar, which was made in ABS plastic.

| However, unique to the **Apple Extended Keyboard II**, the "Power" keycap has flat profile. This differs from its predecessor, which had the same profile as all the other keycaps in its row. | The "Power" (**◁**) keycap on the **Apple Extended Keyboard II** has the same flat profile as the 2U Power key on the [[Apple Standard Keyboard]]. This differs from the Power key on the previous [[Apple Extended Keyboard]], which had the same profile as the other keycaps in its row. |
