Apple iMac (17-inch Mid 2006) - Manual (Page 89)

iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — Logic Board
Rotate the unit so the power supply is in the bottom right corner and the optical drive is on
your left. With a black stick, disconnect the power supply cable on the underside of the logic
board.
Pull the board toward you and slightly lift the board up. Note: The I/O ports fit tightly into
the port hole openings on the rear cover. You may have to fidget with the board a bit to free
the ports from the rear cover. Remove the logic board out of the rear housing.
