I play the CDs and then file the box, with all contents, on a shelf with other boxed sets of the same kind of size. I may even get it out and play the CDs a second time. Or not. I've really slowed down on buying stuff.

Same here. I used to judiciously rip the CDs to iTunes before storing them in the book cases, but I've even stopped doing that because I have too much of a backlog. I stream more often than listen to my old, cracked iPod these days.
