So summary for now:
The system works fine and the hard drives are being detected and mount fine.
I would want to upgrade the Kernels at some point to use be update but for now this works OK.
Originally i was planning to run Yunohost but sticking with https://syncthing.net/ for now.
One additional question (I realize I might need to open a new thread for this.)
How can I use the ATX Pins on the board, i.e. the power button, reset button etc.
Thank y'all for your help! much appreciated.
