I've got Kallax 1x4's for LPs (around 8 of them as I don't trust the stability of the other combinations), for my 45s I keep them in swanflight cases for the majority (15 200 boxes plus some 100 boxes) but also have storage from 1-qubes (don't think they exist any more) that take around 150 45s each and I've got 7 or 8 of them
