I wanted to build a computer that will run all the games I want to play at the least amount of money possible, so over time i accumulated these parts for a good price and only spent about 500 on the whole desktop. I had a few accessories and bought the monitor at Best Buy.
Overall I am extremely happy with the setup, the only downside is that most fps games (Planetside 2 for reference) ran around 30fps, and minecraft runs at ~70 with mods. I had to upgrade from a WD Green 500gb to a WD Blue 1tb because I used a lot more room than expected, but other than that upgrade I will want to upgrade the graphics card soon (Could be to a 7790).
Sides notes: I'm running windows 7 pro, at a 3800mhz cpu clock, and have 3 fans for the case/cpu. Some parts were purchased used (mint) to save money (ram, original hdd, dvd drive, cables). Everything else was new/on sale.
Future possible upgrades: Cpu to a fx-4300, fx-83xx, or the newest cpu. Graphics card to a 7790, or ~160 dollar card. DVD drive to a blue ray drive. Power supply to a 500+ modular. Networking card to something good and cheap.
