Teardown of iMac 24 inch (2021, M1 CPU)

Objective

• Purpose: To explore the internal components of the iMac 24 inch (2021 model) with an M1 CPU, specifically focusing on a cracked screen.

Process Overview

1. Power Down and Disconnect: Turned off the iMac and disconnected the power cord.
2. Cutting Adhesive: Used a metal prying tool to cut the double-sided adhesive around the edges, similar to an iPad screen replacement.
3. Screen Removal Challenges: Encountered difficulty due to the cracked screen; had to cautiously separate the screen to avoid damaging the LCD or internal components.
4. Internal Inspection:
   • Observed the internal layout, noting the minimalistic and simplified design.
   • Examined the motherboard, fans, and other components.
   • Identified the speaker, Wi-Fi antenna, and possible Bluetooth module.
   • Noted the integration of components onto the motherboard, including RAM and storage.

Key Observations
