I went the opposite route. I have over 1000 CDs and numerous DVDs and finding the right amount of rack space was very overwhelming. I decided to get rid of the racks (nice to have my living space back) and use binders. I went the budget route and buy the 3 ring binder sleeves ($20 for 200 discs) and use 3" or 5" zippered binders. I save $$$ by using school quality binders, not the leather type from case logic. It's not the most high quality, but it gets the job done. I just store the multiple binders in a closet and get rid of the jewel cases.
