Mine is from early 2016; I didn't build it, but I did pay for it to be custom built. I have also made a few additions since then;

CPU: Intel Core i5-6400
CPU Cooler: Cooler Master Hyper 212x
RAM: Corsair 3000mhz Vengeance LPX DDR4 (4x4GB for a total 16GB)
Graphics Card: AMD Radeon R9 380 4GB
Motherboard: Asus Z170-K
Hard Drives: Seagate 1TB (Hybrid w/ 8GB SSD)
Kingston 240GB (SSD)
Case: Corsair Carbide
PSU: 550W Corsair VS

And I got a Tytan 5.1 Surround Speaker Set at Christmas, which I'm very pleased with.
