Looking for a way to store alot of audio CD's, in their jewel cases versus sleeve systems



I have amassed quite a few CD’s and like the look of the CD sleeve systems, but I am a little concerned that if I try to sell or trade a CD, alot of stores will want it in it’s original jewel case. Also, I read that storing CDs vertically is best. I dont have much space, so building big shelves & cabinets is not really an option.

Also, sleeves would be a little awkward if I am playing a Cd alot, I am taking it in & out of the sleeve alot.
