The Chieftec BX-02B-B-B 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 and Micro-ATX. The dimensions of the case itself (LxWxH) are 540mm x 205mm x 522mm.

The Chieftec BX-02B-B-B 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 four 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. There are no 2.5" drive bays, though, so any SSD or laptop-sized HDD installation would require an adapter. Installation of hard drives into these drive bays is made all the more easier by screwless rails that allow tool-less mounting.

Made primarily of Steel, the Chieftec BX-02B-B-B 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.
