there right anyone with any computer knowlage knows that alienwere adds like 50 dollors on each part you buy, if you made the same one you would probably save 300 dollors per 1000 you spent on there system's, no need to buy alienwere anyway, make your own for much cheaper, or go with a prebuilt computer and just upgrade it, i would build my own because then you know what your paying for if you wana upgrade to 2 sli cards in the future you can or 8 gigs of ram
