Setfree

This is my current build. https://pcpartpicker.com/user/justin12101992/saved/dKYJVn I just stumbled across unraid a few days ago. I have my computer, monitor, and tv set up in office. What im trying to accomplish is pretty basic. I just want to play video games on tv and computer. Trying to get it setup where i can play with my kid at same time or friends. Or run game and kodi/plex to tv. With 2 mice/keyboard or xbox controller thru usb adapter. Is my cpu enough? i see alot of people running more server side cpu stuff....more cores... Is my Ram enough to have do this fast? My current build already ate a whole in wallet. But i can spend maybe $1000 more. Suggestions? And any pointers on how to do that setup once i dive in?
