You'd be better off towering your a1200 then trying to find an extension cord to the cpu slot because: 1) they don't exist, 2) the delays when accessing the custom chips or chip ram would be intolerably slow and would probably crash the system.
That being said, you could probably keep using your keyboard case and keyboard with the
Keyrah adapter and use that to connect to the motherboard in the tower case.
