I have an ASUS M4N72-E motherboard that I didn't really know what to do with so I decided to sell it. I did some searches to get a general price range for what to sell it for but I couldn't find anyone selling this motherboard, it seems it has been discontinued. Does anybody here know a good price for it? It is in decent condition, a little dusty, and has a rust spot on the bottom of the motherboard located on the metal bracket underneath of the CPU.
