The GM Corporation C20 has a the Micro-ATX form factor. Micro-ATX is a smaller version of the ATX standard which is designed to make your case and the system therein lightweight and portable. The dimensions of the case itself (LxWxH) are 380mm x 137mm x 375mm.
The GM Corporation C20 has four expansion slots, so there is some 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 four 5.25" drive bays, which is enough to house an optical drive and a couple of hard drives, but with just one 3.5" drive bay there is not much extra drive space available. What's more, there are no 2.5" drive bays, so mounting an SSD would require using an adapter and filling one of the few drive bays available.
