The presence of a special filter in the housing to prevent dust from entering. Without such a filter, dust settles on the system elements; Radiators are especially susceptible to this; they also lose their efficiency by becoming clogged with dust. If you have a dust filter, you have to clean not the “filling” of the PC, but the filter element itself, which is much simpler and more convenient.

Compartments for dust filters can be located on the front panel of the case, back, bottom, top, or in the side walls. There are also case models with several technological niches for installing dust filters - the combined version assumes the presence of such compartments on several sides of the case at once.

The presence of a viewing window on the side panel of the case, allowing you to see the “filling” without opening the case. It gives the case a stylish appearance; in addition, it allows you to install a lighting system inside, which is appreciated by gamers compared to case models without a window.

The materials for manufacturing the windows on the side panel are:

- Acrylic. Acrylic or plexiglass is an inexpensive material of relatively light weight, which, however, actively collects scratches and can be deformed when exposed to high temperatures.

- Strained glass. Tempered glass panels have excellent transparency, are resistant to scratches and are easy to clean from dirt. At the same time, they weigh a lot and can break to pieces if not handled carefully.

- Metal grid. Wire mesh is a simple type of window material used on the side panel of a cabinet. It allows air to pass through and provides additional heat removal from the internal components of the system unit; dust can leak through the mesh overnight.
