This was my first PC build, based on Austin Evan's Boson 3.0 $350 build. I changed the case, power supply, RAM (I went with 16GB instead of 8GB), and storage from his build. Additionally I purchased a PCI WiFi card, and a USB header adapter so I could use the second USB port on the front of the case.
Performance isn't mind blowing, but it is a significant improvement from trying to play games on Intel HD graphics. Modern titles are a hit or miss, I can play Fallout 4 at about 40FPS and 60FPS on Overwatch at 1080p and mixed settings (with Vsync off on both).
My biggest complaint with this build is the case. I lost count of how many zip ties I used, and my SSD is taped to the bottom because there is only one HDD/SDD mount.
