I finally decided to upgrade from an older AMD APU build. The video card and WD Reds were carryovers from the old system, but everything else was purchased new for this build.
I'm using the WD Reds to store all of my home media - this machine serves media via Plex, so it also transcodes on the fly.
I probably spent too much on the case, but I love the way the Phanteks Enthoo Evolv ATX looks and it should be fairly future proof. I decided to replace the PWM fan hub that comes with the case and went for the NZXT Grid+v2 so that individual fans could be labeled and controlled.
I'm holding out for the video card because this one works fine for what light gaming I am doing (especially with a 1080p monitor).
CPU is OC'd to 4.4Ghz via Asus's auto OC tool and it hovers around 23 degrees celsius on idle. I haven't had the chance to do any real stress testing - coming soon!
