This is just evidence of the failure of the Facebook ad platform. With the sheer abundance of data that Facebook commands, this should not be the case.
I donno. I was looking for opteron serversm (still am, actually). I don't think there's anywhere that facebook would actually know that. I'd ignore any intel boxes, so they'd have to be pretty accurate to get something that I'd click on.
If I was facebook, I'd focus on social activities that I'd be interested in while interacting with my friends. Ski trips, wii games, etc.
