Thanks for the reply and information. It's good to hear that what I have can work. The only thought on going the Ryzen route would be to hopefully consume less power draw compared to my Xeon rig. Seeing as I currently don't have a Plex Pass any trancoding is done by the CPU and so far hasn't effected anything, granted it's usually just 1 stream, since I didn't realize until it's too late that the Apple TV 4K doesn't direct play MKVs so Plex has to transcode those, hopefully I'll get around to converting them to MP4, once in a blue moon a remote stream.
As for VMs, it would probably be just one Windows 10 VM running fully time with BI, that is if I even decide to move it over from the dedicated box it's on now. But the one I'm really thinking about moving over is my firewall, so that I can retire that box. It's currently untangle, but I might switch it over to opensense, so a single core will run that no problem.
With 6 drives, would it be fine to have just 1 parity drive? Right now 2 of them are parity as that's why they suggest. I have a 7th 4TB drive that I would use for parity and the other 6 would be for storage. At what line do you consider a second parity drive with unRaid?
