You may get lucky, though the last few Cyberstorm PPC boards I've seen on places like Amibay have gone for around the US$1000 mark. Your offering just below US$800 which also includes possible international shipping charges. You also didn't mention in your OP what clock speed you wanted, which does affect the price.
What I'm saying is that you may need to rethink what you are offering for what is a highly sought after piece of hardware, especially when there are other people offering a lot more money to get their hands on one.
