[YAWN]. I guess I'm jaded. I "built" an external floppy drive for my Radio Shack HX1000 computer for about $75 when the going price for the 'external' floppy drive (720K) was about $300. I obtained a case, ac adapter and ribbon cable. I modified them all to make it work, and that was in 1988. So disassembling one of these external drives is pretty much the same. CD, hard drive, DVD, interface board, cable and power supply. Good presentation.
