Need a recommendation on stand alone Windows 10 server

I want to setup a low cost Windows 10 server just for Plex Live TV/ DVR. I’m looking at a reconditioned Dell 500GB, i7-3700 , 3.40ghz, 8gr ram. Does anyone have a setup like this working well with Live TV/DVR ? I don’t think I would be needing more than 2 streams at the same time. Will this work ? Any advise ?
