PSU max lenght

Possible length of the PSU that can be installed in the case.

Graphics card max lenght

The maximum length of a graphics card that can be installed in this case.

Modern mid-range and top-end video cards with high performance often differ in considerable length, which is why such a card can not fit into any case. So before collecting components, it is worth evaluating the length of the proposed graphics card and choosing a case in which it is guaranteed to fit. This forethought is useful anyway, but it's especially true if you're building a system that requires a powerful graphics adapter, such as a high-end gaming PC or 3D design workstation.

Sidewall thickness

The thickness of the side walls used in the case. When choosing a thickness, manufacturers have to compromise between several points at once. On the one hand, thin walls are inexpensive and heat dissipates faster through them, which has a positive effect on cooling efficiency. On the other hand, powerful systems inevitably require thick walls, otherwise the case may simply not withstand the weight of advanced high-performance components. Thirdly, steel is a fairly durable material even with a relatively small thickness. In light of all this, in most models this indicator does not exceed 0.70.8 mm, and more often it is about 0.50.6 mm.

Rubber feet

The presence of rubberized legs in the design of the case.

These feet absorb vibrations generated during operation of the computer (mainly due to the operation of fans and optical drives), thereby reducing noise levels and providing additional comfort. Rubberized feet are especially desirable if the computer is placed on a table (on a tabletop or in a dedicated compartment on a table) or on a hard floor.

PSU mount

The location of the power supply (or seat for the power supply) in the case.

The traditional option is the top location of the PSU, this is a familiar and familiar option for many. However, heated air from other system components accumulates in the top of the case, reducing cooling efficiency. Cases with a lower location of the PSU are deprived of this drawback, however, a lot of dust and other contaminants get into them if the system unit is installed on the floor. However, this difference becomes critical only when using high-performance systems with appropriate heat dissipation; for an ordinary household PC, the location of the power supply unit as a whole is not important.

Also note that in miniature cases like mini-Tower (see "Form factor"), the PSU installed on top can overlap part of the motherboard, which further worsens the cooling efficiency and makes it difficult to install large CPU coolers; however, it all depends on the layout of a particular case.

3.5" bays

The number of internal 3.5" form factor bays provided in the design of the case. Such bays, in accordance with the name, are intended for internal components, mainly hard drives and some SSD modules; to access them, the case must be disassembled.

Theoretically, the number of bays corresponds to the maximum number of drives that can be installed in the chassis. However, in fact, the best option is to install drives through a single slot to ensure efficient cooling. Accordingly, it is best to select a case in such a way that the number of internal 3.5" bays is twice the expected number of hard drives.

Fans (bottom)

The number of fan slots on the underside of the case, as well as the size of the fans that these slots are designed for. The presence of the fans themselves in the kit should be specified separately.

The larger the fan, the more advanced it is considered: a large diameter allows you to work efficiently at relatively low speeds, which reduces the noise level and energy consumption. Case fans are available in several standard diameters, and the seats under them can be designed for both one and several sizes — for example, 120 / 140 mm. At the same time, in some models, the available number of seats also depends on the selected size: for example, it may be possible to install either one 180 mm fan or two 140 mm fans.

Fan mounts total

The total number of places for installing fans provided in the chassis design.

The more performant the system, the more components it includes — the more powerful cooling it will need; therefore, the number of places for fans, usually, is directly related to the size and purpose of the case. It is also worth considering that with the same number, the installation location of individual fans may be different — behind, on the side, on top, etc.

Dust filter

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.
