So I have an old iMac G5 no isight that is no longer working but am making the switch soon to a macbook pro retina. although i will most likely never use it, I would like to convert the dvd drive from the imac i already extracted into a usb external drive (Like an apple external superdrive). How would I go about doing this? I am not sure what the plug it uses is called, maybe someone knows and can help me out. Thanks.
