Does the HP 6005 Pro desktop have an agp slot? I can't seem to find it?

Everybody says it's a brown slot above all the white slots, but I don't see anything like that. There's two chips stuck in two black slots above all the white slots, but that can't be it, can it? Why would there be two? I just ordered the machine so it has all its original parts. I need to remove the old graphics card, and put in a new one, but I can't find it. Any help? Pictures would be helpful too. Thanks!
