Thanks Motorhead. I'll try to post a little more details later but I got 6 cases from 1 sheet of plywood and 1 sheet of 1/8 press board. I put a dado 1/4 inch up from the bottom all the way around to hold the bottom in. I didnt glue them I just brad nailed them together. Now I didnt use the press board on the bottom I had a little thicker paneling left over from a remodel project. If you had to use the pressboard for the bottom I would go a little thicker on the press board for the bottom. But I stress dont use the thicker pressboard for the dividers... they need to be thin. I think they ended up costing roughly $5 a case.
