New Member looking for feedback on components

New member here and new to buildibg computers,

This will be a build for my plex media server and then a nas for files,photos,and such.

Chenbro 4 bay nas case

I should also say I dont know what software to use. I have been debating free as or unraid.

I also found this motherboard.
