As a fellow AMD enthusiast (just upgraded my 1700x to a 5800x) the R7 1700 makes a fantastic unraid server BUT, as a long time BI user you are going to want to use a 6th gen+ Intel cpu for the iGpu Quicksync acceleration features. Without Quicksync my old i7-6700k in a dedicated box would be at 75-80% use all the time with 8 cameras, with Quicksync on it would sit at 18-20%. I now have 12 cams on the same system and it pretty consistently sits between 23-28% depending on how windy it may be that day. I would split BI off into a seperate box. Those cheap Plex transcode prebuilts are great for this since most of the work is on the iGpu it does require more than an i3 with that amount of cams. Good luck on your build!
