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.
3.5" external bays
The number of
external 3.5" component bays provided in the case. The name "external" means that the bay has an exit to the outside (usually to the front panel), and can be reached without opening the case. One of the most popular options the use of such slots — the installation of card readers; in addition, they can be used for other components — in particular, USB hubs.
The number of bays corresponds to the number of external components that can be simultaneously installed in the case. However, this form factor is not particularly popular in the outer periphery, so cases with more than 2 such compartments are rare.
Screwless
The ability to use special latches (instead of screws) to mount peripheral devices in 3.5" and 5.25 bays, as well as cards in expansion slots. This
screwless mounting greatly simplifies the installation and replacement of system components.
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.
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.
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.
