I put together this list of parts, i don't know if its any good but, i want a gaming pc, and i thought these parts would be just fine. I'm not sure about the mobo and the cpu combo, but i don't plan on overclocking so i think it will be ok. If you think anything could be replaced, please let me know.
CPU: i5 6500
Mobo: Asus h170 pro gaming
GPU: EVGA 1060 Super Clocked
Storage: HyperX Fury 120gb SSD, 1Tb WD Blue
Memory: HyperX 2X4gb DDR4
PSU: EVGA 600 B1
Bonus question. If my case fan has a 3 pin and a Molex, do i have to use both or just one?
