I really don't know anything about this one.My tech left it in a bin without much of an explanation -- I assume that it works properly, since he normally tosses bad boards.However, I have no idea and can offer you no guarantees.Price set as a reflection of this, but feel free to reach out with any additional questions that I will not likely have answers forSold as-is, what you see is what you getYou can tell that it was removed from a computer in recent years. Might just need some duster and contact cleaner (in addition to a CPU and all the other stuff)Once again, I don't think that he would put it back into the anti-static bag if it had issues -- no signs of actual damage. Needs TLC and expertise.
