I first built this PC in the summer of 2012, and have been using it for gaming and school. Got the CPU/mobo for $220 at microcenter, and didn't pay for windows, so the actual price is about $735. I recently upgraded the GPU from a 460, and upped the PSU from a 430w. I have the CPU overclocked at 4.0 ghz, so I'm able to use htc vive smoothly. I feel the parts have a great performance/price ratio. I'm frugal when it comes to money, and this mentality translated to building the PC. I didn't want high-end, as games never really require it and I could't really afford it, and future-proofing is near impossible. So I went with a good middle ground. By the way, I'm aware that the cable management is horrendous but I don't mind the cables everywhere scifi feel :D
EDIT: Redid cable management.
