Well, the fact that it's not actually available anywhere, except at outrageously ridiculous prices from a couple of third party sellers, probably has a lot to do with that. Nobody really talks much about boards they can't get. Plus, that board really isn't all that terrific anyhow. Indications are that it has blind doubled 6 phase VRMs, being called 12 phase, so it's probably a good board but not worth anywhere near the asking price of the few limited sellers.
Amazon and Newegg have exactly zero of them for sale unless you go through a third party seller.
