I had a fairly high budget for this, so I wasn't min-maxing price/performance. I wanted high end, though not crazy overkill, and quality components. Build was mostly bought in June/July and completed in July 2016.
This was mostly intended to be a gaming PC, but I loaded up on RAM because I do a little bit of Photoshop and Acrobat work. Also, because I could.
I replaced all the case and cooler fans with Noctau to keep it quiet. I did the math on case fan pressure and made sure the layout had a balanced case pressure to ensure little dust collection.
I'm very happy with the Phaneks Enthoo Evolv ATX Glass case. It looks fantastic, and the build quality is good. No sharp edges during construction.
Not listed on the parts list are all the custom cables from CableMod thatreally complete the look. I also added a couple of sets of the 1m Phanteks lighting kits.
It drives many games to over 60FPS at max settings. Though the recommended GeForce Experience settings for The Witcher 3 are a bit under max, lower draw distance, lower hair works, to get reasonable frame rates.
For gaming, the CPU is mostly overkill, I've never seen it over 50%.
I may add a second GeForce 1080 to get that last bit of performance.
