This was pretty nerve-wracking; it's the most money I've ever spent on a PC. I'm just glad I had the help of my uncle and his practiced hands. He's an electrical technician who deals with building hardware for his job.
We were both a bit nervous after initially assembling all the components and seeing UEFI load up with no problems. Unfortunately, we later did run into a problem with the original video card I had for this project: the XFX Radeon R9 280X. The video card driver was causing massive screen flickering and OS crashes. My uncle swears off ATI, and has had better experiences with NVIDIA cards. I decided to get a refund and grab the GTX 760, which was also cheaper.
Until I get the video card replaced, my uncle gave me an old GT 520 card, which still works surprisingly well. I already feel like I'm seeing my games in a whole new light.
Overall, I'm very happy and have enjoyed this learning experience. If anyone's on the fence about trying to build their own PC, find a buddy to help, and, if necessary, bribe them with beer and/or food.
My thanks goes out to xtroria for providing the initial, suggested parts list.
