Features

The direction in which the body is facing. This parameter is indicated only for models that have a certain specialization and differ markedly from general-purpose cases.

Gaming. Cases designed for high-performance gaming computer systems. They usually have numerous openings for expansion slots and bays for drives (see the corresponding paragraphs), as well as advanced options for installing cooling systems — many “seats” for fans, the ability to use liquid cooling (see “Liquid cooling support”) and etc. In addition, they often stand out due to their design: they can be equipped with decorative lighting, transparent windows, etc.

HTPC. Enclosures for PC multimedia orientation, the so-called Home Theater Personal Computer (HTPC). The characteristic features of such cases are compact size, the presence of additional buttons on the front panel for controlling multimedia (and sometimes a sensor for the remote control) and an advanced design.

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.

Fan max height

The highest cooler height allowed for this case.

In this case, we mean a cooler used to cool the processor — such a component is found in the vast majority of modern PCs. Height is measured relative to the motherboard.

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.

5.25" bays

The number of 5.25" form factor bays provided in the case design. Such bays are made only external, that is, they can be accessed from the outside without opening the case (unlike 3.5", see the corresponding glossary items). Today, 5.25" bays are mainly used for installing optical disk drives, internal hard drives in removable pocket adapters (Mobile Rack), and sometimes additional fans. Also, 3.5" devices can be installed in such bays using special adapters. ". Most cases are equipped with 1 5.25" bay or two bays. But there are models with 3 or more bays, as well as cases without external bays.

internal 2.5" compartments

The number of internal 2.5" bays provided in the case design.

Such bays are mainly used for installing internal hard drives and SSD modules; The 2.5" form factor was originally created as "laptop" form factor, but recently it has been increasingly used in components for full-size PCs. At the same time, when evaluating the number of these bays, note that drives are recommended to be installed through a slot; so in Ideally, the number of bays should be twice the planned number of drives.

Also note that some cases use combined bays: initially they have a size of 3.5", but if desired, they can be converted to 2.5". These bays count towards both 3.5-inch and 2.5-inch slots. In fact, this means that the total number of available slots is not always equal to the sum of the number of both. For example, a case with 10 3.5" bays and 6 2.5" bays can have 4 combined bays, and the total number of slots in this case will not be 16, but only 12.

Fans total

The more fans provided in the design, other things being equal, the more intense the cooling will be and the more powerful (and, accordingly, “hot”) hardware can be placed in the case without the risk of overheating. For everyday tasks, a case with one, two or three factory fans is enough. At the same time, when comparing, it is worth considering not only the number, but also the performance characteristics of the fans (diameter, speed). Also note that there are cases without fans on the market with free space for fans, which allows, if necessary, to supplement the cooling system and improve its performance.

Fans (back)

The number of fan slots on the back 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; specifically for the rear panel, the size up to 92 mm is considered relatively small, 120 mm — medium, 140 mm — large.

Most often, the holes for installing fans are designed for one specific size, however, there are also “multi-size” seats, for 2-3 options in diameter.
