as for another solution to connecting a CDROM to a 1200 without towering it is this................get IDEfix with the little hardware and just connect a regular internal PC CDrom just hanging out of the back of the 1200 with a cable long enough.
The real A1200 feeling! :-D
Thats what I got a internal pc CD-Rom connected to internal IDE and a bigger replacement powersupply.
I have a 4way idesplitter so I have 2 of those swapable harddisk bays that is for a 5,25" pcdrivebay as external hd-cases for a 3,5" ide disk and a 2,5".
I have the same swapable drivebays for my pc hds as well.
I really recommend those! Backup is just a matter of inserting harddisk, copy, remove harddisk.
As for using a internal cd-rom as external I never noticed any problems except vibrationnoise sometimes but a bit of antistatic foam took care of that.
