Last thread, I promise. After seeing how much cheaper it is, I've decided to build myself. Just want to make sure these components will play nice together. Anyone wanna help out and look them over for glaring errors or oversights?

A GTX 780 would be far and beyond a better choice for a GPU. It's cheaper, and absolutely demolishes the 290X in performance.
In addition, is there any reason for going Mini-ITX and Micro-ATX for the Mobo and Case?
