The CPU and motherboard was a combo from Micro Center. The graphics card also came from Micro Center. I bought pretty much everything else from Newegg. I waited for sales before buying stuff.
I get near 150-180 fps(on ultra) in Rainbow Six Siege, so it works well for my 144hz monitor. CS:GO, and Minecraft are a breeze. I built this a few hours before a LAN party, it was fun playing with a brand new computer.
The grand total(including tax and rebate) for me was $944.08.
