·I can only speak personally, but there’s almost no way I’d buy a 3647 with a heavily polished case and without a serial number. The only exception would be if the price was irresistibly low. I’d want at least €1k less than a normal case with SN, and I’ve got a sharp midcase in the parts box so could correct the problem. You’d encounter problems if you ever tried to sell it. They’re not exactly rare so why bother ?
