This started as a very basic desktop for general use and light gaming that I put together back in early 2013. In the last several months, I've been replacing components one-by-one and now the only remaining original part is the crummy Toshiba HDD that I use as backup storage. With the glut of awesome deals from Black Friday through Christmas (2014), I got some killer deals on pretty high end stuff. I'm very pleased with the end result, and this thing runs great. The last updates were the XFX R9 290, the XFX PSU and the Raijintek Aidos CPU cooler.
