Right now only 7bit wants the 7BITSPECIAL

. The holes betweent the 6-pack (PgUp, PgDn, Inst, Del, Home, End) and arrow keys would be covered by the Fico keyboard case. but if you don't put switches there, it will be fine. If you put switches there, you will not be covering the keyboard with a case, or you will need a custom case made, or butcher your existing Filco case by cutting some of the plastic out.
there are no cheap filco cases that we know of. You would either reuse your existing Filco case or find a way to make a custom case. there are some effort going on around that, but I don't have high hope. I have loaned out one of my filcos to a friend's friend for 3 months now so he can digitize it with his computer and mill a case for me with his personal CNC machine in his garage. But I don't have high hope with that
