The goal is to use this as a NAS storage server that mostly runs Plex (3 simultaneous transcodes max, 5-7 simultaneous direct play max)/Sonarr/Radarr/Tautulli and some other dockers. I have a few 8TB WD Reds in my current set up - I would also need to figure out how to migrate things over and reformat those drives to add. I guess I should also mention this will be my first custom build. Would appreciate any comments that could either make this a better build, cooler(?), or save me some money.

Thanks in advance. Looking forward to being a part of this community.

That hardware overall should work great for your listed applications.

 

If at all possible I would get 2 sticks of memory for dual channel.  For the purposes you listed, you don't need the wired network adapter.
