It is not necessary to peel all of the EMI tape off the optical drive bracket. Only peel up the portion highlighted in red that is attached to the body of the optical drive.
Peel back the portion of aluminum tape highlighted in red, leaving the rest attached to the black plastic optical drive bracket.
Great How-to, except the how to find the replacement Optical Drive... Can't find the 2428 online anywhere. Any help with the part number before cracking the iMac apart would be greatly appreciated!
Great tutorial. Now if I wish to replace the Superdrive by an SSD (the Superdrive is dead), since the SATA port of the Superdrive is 3Gb/s only, can I keep the Superdrive cable for the SSD but swap it plug to the free SATA III port on the motherboard? Or do I need a new cable?
