How reasonable would it be to design a case with 3.5" _external_ bays for floppy, Zip, and memory card readers positioned with drives mounted vertically (either with the disks being inserted in and ejected out the TOP of the chassis, or out the front with the drive mounted on its side)? I've seen floppy drives mounted on their side, but would a Zip drive face issues from such positioning, given their notorious "click of death" epidemic?
