PS2, XBOX, and GCN are all in vertical metal DVD towers from Sam's club. They each hold 84 games or DVDs and only cost $18. Genesis, Sega CD, and 32x are in a bookshelf. N64 and Super Nintendo games are in those little wooden crates they sell for CDs with the crates stacked two high on bookshelves, creating a double shelf. DC games are in horizontal CD cases on top of the bookshelves, NES games are in a smaller wooden rack made originally for VHS, PS1 games are in one of those wooden multimedia racks. GBA, GBC, NGPC, and Gamegear games each have a tupperware like storage box, and the old spinach color gameboy games are crammed into a big zippered case meant to hold a gameboy, games, accessories, etc. Another solution if you don't care about cases is to get a big ass CD binder. I got one that holds 240 disks without putting them back to back in the pockets for $12 on clearance at Target.
