Can I Buy These New Still?



you can try to give them a call and see if they have any surplus parts.that's probably your best bet.
 
I think he is after that large EVGA logo, which is pretty cool. They should totally make that a standard offering.

Mine is pretty similar to the 'GTX770' classified backplate with all the little mesh pieces. Almost certain those will fit other boards, EVGA doesn't change their designs that much.

Found these ROG and Nvidia logos:

Also some interesting models from bitspower and alphacool. Most of them are pretty much just plain backplates.
