[Build Help] Trying to build the least expensive gaming PC I can

I have been a console user for a while primarily due to cost restraints, but with the next iterations of consoles coming onto the scene soon I was thinking about getting into PC gaming...

I was reading this article, and was wondering how a computer like this would handle most games on medium settings. Has much changed since this summer when this was published? Is there a way to cut down even more on price? The lower the better while still handling most games and looking decent is what I'm aiming for.
