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.

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.

Lighting type

The type of illumination provided in the body design.

The backlight plays mainly a decorative role, it gives the computer an original appearance, which is appreciated by fans of external tuning. Lighting can be mounted separately, but it is easier to purchase a case where it was originally provided. The types of illumination can be as follows:

— Illuminated fan. One or more coolers are illuminated, facing the side or top surface of the case.

Cases with backlight. Separate parts of the body are illuminated, usually from the inside, in such a way that the illumination can be seen through a transparent window / windows or a lattice surface. Sometimes external lighting can be provided.

There are cases in which both types of illumination are provided simultaneously. And for office needs , cases without backlight are suitable.

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 (front)

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.

Fans (top)

The number of fan slots on the top side 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, 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 chosen size: for example, there are gaming cases where you can install either one 180 mm fan or four 120 mm fans at once.

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.
