I had one of those. The shop I bought it from refused to replace it from their inventory, all they would do is take the motherboard, send it back and then give me the replacement some weeks later when the RMA process was completed.

Since I needed that machine functioning, I never replaced it (the mobo had some extra SATA ports handled by a different controller, so they kept working and I switched to using them). I suspect a lot of people are in the same boat. I'll never do business with that store again.
