I'm right now using my one and only PC as a gaming/work/media server rig. It's an i7-4930k, 32GB RAM, GTX 780Ti system, and my MKV files are stored on a 2TB external HDD. I have Plex Media Server installed on my PC and use my Roku 3 as my media streamer. All this is in my bedroom where my PC, TV, Roku are in close proximity to each other. I find my PC a bit too loud for using as a Media Server since it's only a few feet away from my right ear when I'm watching movies due to it being 45 degrees from my right ear and a few feet away when I turn around to sit and watch movies through my Roku. Would it be redundant to buy a dedicated low cost pre-built PC like a Dell Inspirion with an i3-4150 to use as a Plex Media Server?
