    • Tilt the top of the logic board away from the rear enclosure.

    • Lift the logic board straight up and out of the iMac.

    • Be careful not to snag the board on any of the rear case's screw posts.

    • The I/O boards at the bottom of the logic board will be the greatest challenge. It is recommended to pull gently to avoid any damage.

    • During reassembly of the logic board, pay attention to the position of the I/O connectors. When the board is back in the case, insert a USB or Thunderbolt cable into one of the connectors to align it perfectly.
