The Cooler Master Cosmos II has a the E-ATX form factor. Extended ATX is a slightly deeper version of the ATX standard which is designed to provide all the advantages of ATX but with slightly more room. Using the E-ATX standard, the case can house motherboards and power supplies with form factors ATX, E-ATX, Micro-ATX, XL-ATX and Mini-ITX. The dimensions of the case itself (LxWxH) are 344mm x 704mm x 664mm.
The Cooler Master Cosmos II has eleven expansion slots, so there is plenty of room for extra components, which may be a deciding factor when planning on the longevity and build type of a PC system. The case has three 5.25" drive bays, which is enough to house an optical drive and a couple of hard drives, while still having space for plenty more HDDs with the nine 3.5" drive bays that are also available. You can even install an SSD or laptop-sized HDD using one of the nine 2.5" drive bays.
Made primarily of Aluminium, the Cooler Master Cosmos II is built to be strong, lightweight, and well-ventilated. This often comes at a price premium, but some see the benefits to be completely worth it. 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.
