That's strange...I've always built my computers, so there are no serial numbers on them... Our shipper (Contour Logistics) didn't ask for many details (most boxes were listed as computer, electronics, dvds, books, clothes, spices, OTC medicine, etc...all very generic). This may have been partly because our stuff came over under my student visa as things for studies/living which we will be (theoretically) taking back with us when everything is over. Also, we didn't have anything exotic like corpses, guns, depleted uranium, medieval torture devices, unidentified white powder, etc. When we received our belongings (fifteen years later, or so it seemed), it didn't look like anyone had opened them (our horrible packaging/tape was the same), let alone looked at them.
