I once helped a friend "towerize" his A1200. It was such a hack job but it worked... up until we tried to replace the internal keyboard with an external one. That part required soldering and neither of us knew much about how to solder nor did we have the proper equipment. Needless to say we never got the external keyboard to work and after that no other part of the A1200 worked either. We tried to get it fixed but there was only one Amiga repair shop in town at that time and unfortunately it closed down before they finished fixing my friend's A1200.
Sadly, my friend bought a PC after that and has no interest in returning to the Amiga scene. :cry:
