The intersting part will be the interface.  The quick and easy way would be to take the parellel cable and run it out the back and back into the port.  Kinda ugly but would be easy.  Can tear it apart and see if it looks like ther is an IDE style conector inside and a parellel adapter to bypass and just hook into you're IDE cable's but I seriously doubt that it would be that easy.  If you do enough research you may find a pinout of the drive and solder in a IDE cable but that kinda stuff is hard to come by and even harder to do.  As far as physically making the drive fit that's easy.  Just remember the dremel is the modder's best friend.  I actually have two.  One's multi-speed 110v and one's two speed battery operated.  Use 'em all the time and love 'em.
