Mine appeared to have been opened also. I didn't notice any finger prints though. Perhaps those of us with rattling problems are the victims of a saboteur.
I got mine from the egg. Maybe some nvidia fanboy broke into the warehouse and was messing with the fans. Hehe.
I opened a support ticket with Sapphire regarding this rattling issue. I will report back on what they suggest/say. My guess would be an RMA, but who knows. With such limited stock I am somewhat afraid to choose the RMA option.
I noticed that the Sapphire HD 5970 was no longer on Newegg earlier this evening. It was not even listed any longer. I wonder why that is.
Looks like it's been deactivated: http://www.newegg.com/Product/Produc...82E16814102863
