Building my first computer

[Turnipdude]

I have about $500 and am hoping to build a system so I can play minecraft, WoW, and LoL on decent settings. I have a monitor, mouse and keyboard. Looking for some tips in the right direction for what I should be looking for.

Assuming 1080p monitor? $500 USD?
