I just received 3 741s from MinerWarez this afternoon. The ones I received are definitely used and have some dust in the fans and on the wires (but no bugs from what I can see). They were not in the sealed plastic bags like the ones I received from Canaan in the past and the boxes weren't taped up on the ends either (one was partially open when the FedEx driver handed it to me). I'm off to test them out and hopefully they all work. But I agree that they shouldn't be marketed as "new" on their website.
