i am in intel camp lol ... my NAS is freeNAS in separate room cause its fans are freaky noisy
As they say you get what you pay for....lol. My fans operate on temperature control...very quiet. My drives never get above 29C.
I built my server long before NAS existed. There was a time that I had to have the latest and greatest, now I skip a couple of generations between upgrades. With the upgrade to my server, I may be able to eliminate my Windows PC altogether. From what I have been reading, under Linux, Windows wants a minimum of 4 cores and runs much better with 6 cores. The new Ryzen 2 CPU's do have up to 32 cores. My Win PC has a FX 8350 4 Ghz with 8 cores that I rarely get above 40% utilization with Win 7. I just used MC to analyze about 30k FLAC tracks. Using 6 cores and pulling files from my server, I averaged 108 tracks per minute. I think 12 or 16 cores with 32 GB of RAM should crush anything I can throw at it including up-sampling videos.
I haven't verified this, but, I believe that UnRaid will create a constant back up on each write to disk if you are running Widows under Linux and using it as your main PC. (They use 1 or 2 parity disks and a cache disk depending on your paranoia. lol)
Your analysis of the current state of the technology looks spot on. I am not ready to jump in at this point but I want to monitor the developments and track those soles who like to be on the bleeding edge of Tech. I think the Ryzen CPU's have been out long enough to start looking to upgrade on the next sale. I suspect that JRiver has been looking at this for awhile. I certainly hope they weigh in on this technology soon. They have done a good job of staying on the leading edge.
I have dabbled with bluetooth but it doesn't have the range I need.
