Hm, that is a weird situation, since they were all made by FlexTronics you would think that if nvidia decided to put a serial number on them, ALL of them would have em. And if nvidia didnt tell flextronics to put a serial on them, then NONE of them have a serial and evga should know that.
What i would do is this
Shoot off E-mails to evga and nvidia and post rampintly on evga.com forum.
Call Evga and Nvidia and dial random extentions untill you find someone high up and complain
Drive to Nvidias HQ and run around their offices screaming insanely untill they give you a new videa card!
