This is the rear chassis enclosure for the Apple iMac 24″ M1 (2021), specifically for the Model A2438 with four USB-C ports on the back. It serves as both the structural support for internal components and the external aesthetic panel.

• Magnetic Display Support: Integrated magnets and alignment points ensure proper attachment of the display panel.

• Camera and Microphone Cutouts: Precisely milled areas for FaceTime HD camera and mic port alignment.

Installation Notes:

• This housing is not cross-compatible with the A2439 (2-port version).
