Yes, there's something appealing about the idea of owning a big encyclopedia... but it will most likely be dead weight on your shelf. A lot of dead weight. There's a reason people don't want to ship that stuff. Consider a smaller set with 3-5 volumes, there's already a lot of information in these. (Also visitors won't mock you for it.)
Having that large set in PDF format would be cool, though... Unfortunately I only found the single-volume Brockhaus from 2011 online and that's not very good.
