Keep in mind that this computer is excessively powerful for the average gamer, and it's pretty expensive, too. Also, since I built this about a year ago, there are newer version of certain parts, like the CPU, motherboard, and graphics card.
Case: Fractal Design Define R5
Motherboard: Gigabyte G1 Gaming GA-Z170X 7
CPU: Intel Core i7 6700K
CPU fan: Enermax ETS-T40F-W
CPU water cooler: Corsair H115i Hydro Series
Thermal compound: Arctic Silver 5
RAM: Corsair Vengeance LPX DDR 4 32GB
Graphics cars: EVGA GeForce GTC 1080 SC
SSD: Samsung 850 EVO 500GB
Power supply unit: Corsair RM650 X
WiFi card: Asus PCE-AC56 802.11ac Dual-band Wireless AC3100 PCI-E Adapter.
LED lighting: DeepCool RGB 330
All those parts came to a total of around $2,000. I must add that I had little regard for money on the day I decided to buy these parts, which is incredibly silly. At the same time, this computer will last me a long, long time, and I won't need to buy parts for several years to come. And as I mentioned earlier, I went with quality over value for this particular build.
You can buy the LED strips I bought here.
