Roon and Naim Streamers (Choices and Problems)

Advice please for NDS with Roon. I would really apreciate it. I am a total layman so would appreciate simplicity

I want to us Roon as I am very disaitisfied with Naim app.

How do I set this up?

I have a Sunology NAS DS218j, NDS and Minimac

My questions are these:
Core questions:

  1. Can I run Roon on the NAS ? I understand that Roon core should be on a SSD which I could add, however is there enough RAM on the DS218j? I think not…unfortunately as it does not have enough RAM and Armada 385 processor
  2. My Minimac is 2011, CPU 2.Ghz i5 with 8GB Ram but has no SSD; could I run the core on this as it has no SSD?
  3. So if I cannot use these what is the cheapest option: I see Wilco recommended SONICTRANSPORTER I5? Or should I just buy anoth minimac so I can use it for other things

Roon talking to my NDS

  1. How do I get the Roon RAAT to communicate with uPnp to my NDS. I understand that there are various devices for this?
  2. Can this all be done without altering the SQ?

Thanks in advance, this is a bit of nightmare and all driven from frustration with the Naim app.
