Nice job there r0jaws. Good photos and comentary.
You can get that second floppy drive back inplace by fabricating a backplane out of heavy rigid plastic sheet and some aluminum rails to mount the harddrive on and place it just like the other harddrive. Take a look at the Supra Wordsync 2000 for reference.
Dug out my A2000 recently and started upgrading it.
What brand/version CDrom do you have installed?
Laterz.
