The Helios Prophecy has a the ATX form factor. ATX is the most ubiquitous of case standards, providing the largest array of compatible hardware on the market. Using the ATX standard, the case can house motherboards and power supplies with form factors ATX and Micro-ATX. The dimensions of the case itself (LxWxH) are 526mm x 250mm x 540mm.
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 eight 3.5" drive bays that are also available. You can even install an SSD or laptop-sized HDD using the one 2.5" drive bay.
Made primarily of Steel, the Helios Prophecy 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.
