The case has nine 5.25" drive bays, which is more than enough to house various drives, particularly optical drives. With eight 3.5" drive bays there is also plenty of extra HDD space as well. You can even slot in an SSD or a laptop drive in one of the nine specifically designed 2.5" drive bays

Made primarily of Steel, the Cooler Master Storm Stryker is built to be strong and well-ventilated. Steel cases are generally fairly cheap and sturdy, but also tend to be quite heavy. Whatever your case's material, it is important to keep a consistent airflow so that heat doesn't build up inside. It is therefore advised that you make use of the available built-in case fans and fan installation sections.
