I would get a slot CDR Drive but I have a 72X Kenwood CD Drive and I've been really happy with the speed (trust me, it's noticable) so I'd hate to change. Perhaps I could buy a cheap slotted CD Drive and rip that open and try and put them together or something. But since nothing is standard, I doubt they would go together as well as I'd hope but maybe...
I'll let you know if I find anything.
