I have 2 of the HC's for the 285FTW. I bought the blocks separately from the cards though. Looking at your pictures it seems that you have the 2nd rev of the 285, I am pretty sure in thinking they didn't even make a backplate for the original 285's, one of the screw holes is in a different place. Also, I don't think EVGA offered a block for the 2nd revisions.

Pity you never got your card fired up, as I very much doubt it had the 720Mhz clock speed! Anyways, that definately isn't the block EVGA used for the rev 1 285's.

I smell a rat, and that rat looks like your vendor, or whoever they buy their EVGA products from.
