Truth is this is an item that is almost impossible to put a price on. You are probably getting IMs with offers, so that might be a good indicator of what it is worth. As long as people know that it is not plug and play and in fact will be a difficult installation, the sky is still the limit here. While I am not a flipper, I would still ask a ton for this item otherwise you will watch the buyer turn around and sell it for thousands after you gave them a great deal. The other option would be to trade it plus or minus cash for some other unobtainable part or game that you are seeking.
