I must say, that It’s very kind of you, to take your time to advise me and others 
Well, I have around 5 TB blu ray rips, most in 1080p, but the 4k is increasing. They are all ripped with makemkv, subtitles put inside the “movie-name-folder”,
I have an oooold mac mini, +10y, used it as my PMS, with usb 3.0 hdd hooked up to the mini. But it doesn’t work anymore, too many bugs, so that’s why I’m in the market for a new hardware solution.
I want the Shield, as it can play the lossless audio from my mkvs.
It makes sense, that you say it’s best to split the “tasks” up, in more pieces.
As fileserver and PMS, as I understand you, it’s best to buy a NAS, with a processor, equal or better than the ARMv8, right ?
But then the question is, which one :-))) - it’s a f…… jungle to choose one, imo.
Saw a YT video, from NASCompares, he tested a qnap tvs-h874, sounds great, I want(ed) one, but jesus, that’s too much, to put in a NAS, around 2k usd, without storage :))))
So my next/the actual question is, what NAS to choose, for me ?
Oh, and I do have 2 adult children, they did/will connect to the PMS, and stream from it, so theoretically, max 3 streams at the same time.
Found a used qnap ts-h886, intel xeon d-1622, will it work as PMS ?
cannot find it in the sheet, provided earlier in this thread, is it because it doesn’t have a gpu built in ?
