None of your links work. If I were you I would wait at least a couple of weeks before building because: 1. Intels IB cpu's will be out, AMD will counter with trinity cpu's, hopefully meaning cheaper prices and better performance. 2. Nvidia will be bringing out more gfx cards and more oc cards, which will make AMD drop it's price some. Bottom line if you can hold out a couple of weeks you will be able to buy a powerful HTGPC at a good price.
