DR JoseSPiano: You asked a question last night that I've only just read (yes, I'm CAUGHT UP!).
I am someone who has begun ridding myself of those space-hog jewel cases...those dust-catching, shatter-at-a-glance UNprotective covers that CDs come in.
My solution: Aluminum CD megacases. They come in different sizes, some holding 400-plus, others 500-plus, and the ones I have which hold 1,000-plus. They are also available to hold a greater capacity (up to 2,000, I think).
At any rate, I have three of these cases that hold 1,000. I also invested in gatefold polypropylene covers to preserve my inserts (they will also hold CDs, if you wish to get them for that purpose). You can store a whole lot of these in the space a handful of jewel cases takes up.
First, here's what my cases look like (you can also get them with wheels and a pull-out handle, if you so desire):
