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.

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.

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 0.7 — 0.8 mm, and more often it is about 0.5 – 0.6 mm.

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.

The number of fan slots on the front of the case, and the size of the fans 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 front panel, the size up to 92 mm is considered relatively small, 120 mm — medium, 140 mm — large, and in the most advanced solutions, fans of 180 mm or even more can be installed.

Also note that most often the holes for installing fans are designed for one specific size, however, there are also “multi-size” seats, for 2-3 options. Moreover, these options may differ both in diameter and in quantity: for example, it may be possible to install two 140 mm fans or three 120 mm fans.

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 size of the mounting slot for the liquid cooling system provided at the bottom of the case. In cases that support LCS, water cooling radiators are installed in the same slots as traditional fans. In other words, either a fan (or fans) or an LCS radiator can be installed in the same mounting spot. The size of the LCS mounting slot is indicated by a single number — the length (on the longer side); the width can be determined based on this data. The fact is that modern LCS radiators usually use fans of one of the standard sizes — 120 mm or 140 mm; and if there are several such fans, they are arranged in a row. As a result, the length of the radiator is a multiple, and the width is equal to one of these numbers: for example, 280 mm is 2x140 mm with a width of 140 mm, and 360 mm is 3x120 mm with a width of 120 mm. It should be noted that the same nuances apply here as for air cooling: a larger fan occupies more space and is more expensive but is considered more advanced since it can operate effectively at a lower speed — thus reducing noise and vibrations.

The total number of spaces available for liquid cooling systems in the case, in other words, the maximum number of LCS radiators that can be installed in the case. These radiators are usually placed one per side of the case, so several radiators are often located on different sides: for example, 3 LCS spaces can be located at the rear, top, and front.

When evaluating the number of mounting slots (of all types), it's important to consider that fans and LCS radiators usually use the same mounting locations.

The number of built-in USB-A 2.0 ports provided in the case.

These ports are usually located on the front side. They are most convenient for peripherals that need to be frequently connected and disconnected, such as "flash drives" (for permanently connected devices, it's more convenient to use the motherboard ports located on the rear panel). Specifically, USB 2.0 is considered outdated these days: it provides a data transfer speed of only 480 Mbps and comparatively low power. Nevertheless, in many cases, this is quite sufficient, and USB-A 2.0 ports continue to be used, even in fairly advanced cases.
