I think he wants to convert the clamshell's tray loading drive to a slot loading...That would be a challenge. If you could find a slot loading drive that would fit and plug in you'd have to hope that the firmware would recognize it. Also, the clamshells drive is recessed about 2 cm from the outside of the case...just that in itself would pose a challenge to get the slot to be far enough to the outside to be able to properly insert discs
