My dad Toothless builds exotic rigs for people on a custom order basis. They tell him what they want and he runs over to
microcenter and discusses "nerd/geek-speak" with the techies there and comes back and tells the customer what they really want, based on the bargains, sale items and refurbished and out of box components he can muster, as well as state-of-the-art new components.
Usually saves them about a grand or more and the systems he creates are insane, complete with swapable graphics cards, dual cooling systems and all the bells and whistles.
Microcenter offers a paid for 3 year warranty as well, no questions asked, at an incredibly affordable cost. Anything goes bad, exchange it free with no hassles. They even take mail-in returns/swaps.
Might want to check them (microcenter) out when building a rig because they love helping people make incredible machines.
