I don't like NUC as it does not accommodate my 6TB 3D ISO drive and USB enclosures are just a dead drive waiting to happen (from experience as a full fledged hardware IT guy).

It's too bad because frankly, a NUC is just THE answer for 3D with Kodi.
Perfect image, depth, etc with the right drivers.
And as I said before, combine that with LibreELEC on a flash drive for all 2D stuff and you have the ultimate Kodi machine IMO.
Or should I say when we get the 4K NUCs then these will be the ultimate Kodi machine. I don't care about 4K so I'm set

I will sell my DN2820 and the ODroid C2 in the following weeks and just keep the NUC D34010WYK.

So maybe you should build yourself a small NAS and get yourself a NUC...
