I built this to run games like Rust and Overwatch at decent settings and I wanted to get good frame rates. The parts that I have custom priced are parts that I bought off of an app called Mercari, they were slightly used, except for the power supply which was still in the plastic, but they were way cheaper that what I would have been able to get them for new, which is the main reason I was able to get the PC built in the time that I did. The build process was not too difficult, just the front panel connectors gave me problems. Overall I love the look of it and the cable management was pretty decent.
Update: 4/15/17: Downloaded Rust and when i lowered the water quality settings and turned off motion blur and lens dirt, i was getting 60+ frames (usually high 60 and lots of times in to the 70's!). So happy with how this turned out. Downloading Rainbow Six Siege right now.
Update: 4/18/17: Downloaded Rainbow Six Siege and I am averaging around 100 frames on high settings. On ultra I get around 50 to 60, and as an old console player it is do-able for me, but 100 frames per second just looks so good. Also bought Overwatch and Golf With your Friends.
