Wrong forum section, so the thread will probably get moved.
Looks fine basically. You should probably go for 1600Mhz ram, its almost the same price usually. Processor will work fine but the general recommendation at that price window is usually going to be the 3570K, unless the 2500K is a fair bit cheaper.
In machines of this quality, an SSD is usually a preferred option too.
All of youtr listed oarts wirk together (or at least they should if not defective), but, without giving info on the use for the buils it is impossible to say if it will perform to your wishes. I'd increase the spec on the speed of the RAM, but that would only provide a marginal improvement in performance.
