@Kronus
I going to reply only the part of XBMC/Kodi
Is there any particular reason why you want to have XBMC on HDD??? Cos if you use decent Class 10 SD card it will be much faster than any spinning HDD connected over USB. So do not really see point to do so unless you have some special reason.
Also if you use like 8GB card which cost nothing these days you would be able to keep all whats needed to run XBina/Kodi/XBMC on it.
To use HDD for system, no matter what kind, is not a good move I would say. If you want to connect HDD use it just as storage, nothing else
