This computer is my second build of this type. Part gaming PC and part Hackintosh (eventually). Learned a bunch from the first build, so incorporated that into the part selection. The goal of this build was cool AND quiet.
There are some errors in the parts list for this build:
1) MSI GeForce GTX 1080 8GB Gaming 8G
What I learnt:
1) The NG-D15S takes up a lot of space, especially in this mid size case. This makes accessing the fan connectors around the CPU socket damn near impossible.
2) The Noctua fans keep the temperatures down a lot better than stock case fans.
This CPU is great! Picked it up on eBay for $330. It is a great way to inch towards the performance/enthusiast market whilst staying in the price range of the mainstream processor.
If you don't need those extra 2 cores, really do consider the 8600. I didn't buy it because I wanted that i7 branding and shine. Honestly, if you are focused on gaming, save some money and buy the 8600.
This cooler is amazing! It's big but not too big. It does a great job at keeping the cool and is very quiet! My last build used an h60 AIO (with 2x fans in push/pull) to cool the CPU, and it was loud. I have no regrets choosing the air cooler.
The asymmetric design does very much limit the space above the cooler in the case. So if you want to install a top case fan, check your measurements carefully. Maybe consider the NH-D15 which is symmetrical (and if you have space between the cooler and the GPU).
It is a very tight fit in a mid case, so some maintenance is tricky. Connect as many things as you can before putting your motherboard into the case!
