Might be a silly question so I apologise .
When I get my NUC6CAYS am I better using windows for Kodi or libreelec ?

I've only ever had openelec anc libreelec so not sure what advantage they have over windows .

The NUC6CAYS when I get one will be to watch my movie content from mainly the internal hard drive
Thanks

Depends on your use case, if you only want the NUC for Kodi then LibreELEC is way to go. Small size and features codec support for everything (apart from HEVC 10bit but thats in test builds).
Can fit on a 16GB Usb Drive easily and does not require much resources so 2GB built in RAM will be fine. For windows you would need to upgrade to 4GB as it does slow down.

Excellent , thanks for the reply . Yes purely for Kodi . Would there be any advantage to upgrading ram to 8gb ? Or is it not required ?
Also can all the sound sources dd, dts etc be outputted by the optical out? Reason I ask is my receiver is of 4K so when watching 4K files it wouldn't pass through when using hdmi.
Sorry for what are probably basic question but appreciate your help

Don't quote me as gospel but I believe you will need 2 x SODIMMs for decent 3D performance whichever way you look at it, certainly with broadwell NUCs people couldn't get decent 1080p decoding of x264 without 2 sticks of RAM as the graphics then has twice the bandwidth (not disagreeing with the actual amount needed)
