Are you looking for a full tower case? Or would a mid tower case fit your needs? Some things that would help, how many bays do you want, and how many you plan on using. In my mid tower case I am using 8 of the 10 bays. If you want a front bay for a sound card, fan control, and two or three optical drives, and a few hard drives go for the full tower. But keep in mind you needs.
