Yes, I bought a used motherboard from Amazon. Or rather, a returned one. It could have been returned because it was faulty, because the previous recipient damaged it, because they got shipped the wrong item, because they changed their mind, because they didn't like it, etc. But either it works or it doesn't, it came today, I unboxed it, and it looks fine to me, the only thing I'm worried about is "bent pins" (as that has even happened to some Amazon customers who bought allegedly new boards). To me it looks fine, but my eye is untrained, and this is only my second build.
