A couple of years ago, I took all my CDs out of their jewel cases and filed them alphabetically in large 336 disc capacity Case Logic sleeved cases ($25 each), leaving room under each letter for more entries. The sleeved cases allow quick access and require much less storage area than the individual jewel cases. I was even able to put the associated booklets in the sleeves along with the discs. The jewel cases are in cardboard paper boxes. Just providing a different perspective. As to your original question - I got nothing.
