This will find the cheapest prices for you. Anyway your build looks really solid but you don't have an aftermarket cooler. Stock Intel will not be enough for this rig. Get the Cooler Master Hyper 212 EVO. That is pretty much the most popular air cooler out. The only thing that worries be a little is the tall heat spreaders on the ram. Although it shouldn't be too much of a problem it could be obtrusive in the building. You should also consider getting an SSD.
