The "overseas container" was just hint at the size of his collection That would be about 50m^3 in volume, neatly packed with leaving the monitors outside.
Think of house twice as big as yours, stuffed computer-room on the upper floor, attic cramped with spare parts and a full basement (not just a single room) filled to the ceiling with goodies in orginal packaging ( there was a stack of no less than 5 A1000s in one room).
