Can I ask why you are using the board that you are using?

Is this project to use something you have and make it useful?  Or is it 
meant for others to be able to replicate?

If it's the latter, I'd think that a board that's inexpensive and easy 
for people to get their hands on would be appropriate.  (Maybe the board 
you are using is and I'm just ignorant of that fact.)

I hate to be cliche, but it seems like a Raspberry Pi (et al) qualifies 
here.  It also seems like it has keyboard / mouse / video ports already. 
  (All be it different incarnations there of.)
