No No LCGuy, you said you put your SuperDrive in your 5.25 drive case. If anyone read it, that's what they would have thought you did. Based on the cable pinouts, all the circuits should go to the right place as long as the 20 pin header connection is the same pin configuration as in 3.5 drive headers. Or you might just as well have used a spare external 3.5 disk cable lying around. It should all work. From my perspective there's no reason you couldn't put a 3.5 drive in a 5.25 case. If you are concerned about the 5.25 comment, that's what edit is for. Let's just agree to remove all remarks to 5.25 and no one will be the wiser ;-)
