The Dell Dimension C521 has a the ATX form factor. ATX is the most ubiquitous of case standards, providing the largest array of compatible hardware on the market. The dimensions of the case itself (LxWxH) are 362mm x 115mm x 400mm.
The Dell Dimension C521 has three expansion slots, so there is very little 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 one 5.25" drive bays, which is enough room for an optical drive but little else, and with just one 3.5" drive bay, there is basically no room at all for expansion. With two 2.5" bays, however, there is enough room for a laptop-sized HDD or solid-state drive. 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 Aluminium, the Dell Dimension C521 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.
