The HEC 7106BB 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 438mm x 426mm x 154mm.
The HEC 7106BB has seven 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 a couple of extra free hard drives with the two 3.5" drive bays that are also available. To mount an SSD you would require an adapter, however, as there are no 2.5" drive bays.
