We had two Expedit 6x6ft units in our old house and left them when we moved. Our excuse was that they were bolted to the wall (toddler friendly) and "fixtures". We tried to move something similar previously and it was never the same afterward. In our new home (bigger) we bought 7 Expedit units of different sizes and are essentially treating them as disposable here, too. That said, I don't really see much purpose in spending lots of money on solid wood bookshelves that aren't built-ins.
