Motherboard support
The type of motherboard for which the design is designed. This parameter is indicated by the form factor of the "motherboard", under which the case is designed. The options might be:
—
ATX. One of the most common types of motherboards today, the standard ATX size is 30.5x24.4 cm. It is used in both home and middle-class office PCs.
—
XL-ATX. The general name for several standards of motherboards, united, as the name implies, by rather large sizes and corresponding equipment. Specific values for these dimensions can vary from 324 to 345 mm long and 244 to 264 mm wide, depending on the manufacturer and model. Accordingly, when choosing such a case, it is worthwhile to separately clarify its compatibility with a specific motherboard.
—
E-ATX(Extended ATX). The largest type of motherboards, under which modern cases are made, has dimensions of 30.5x33 cm. It is usually used in high-performance systems that require numerous expansion slots.
— micro-ATX (m-ATX). The compact version of the ATX board has dimensions of 24.4x24.4 cm. The main scope of such boards is office systems that do not require high performance.
—
mini-ITX. One of the further reductions in the form factor of motherboards after
m-ATX assumes a board size of about 17x17 cm and one (most often) e
...xpansion slot. Also designed for compact systems that do not differ in performance.
— Thin mini-ITX. A modification of the mini-ITX described above, designed to reduce the thickness of the case (up to 25 mm), and the RAM sticks do not protrude upwards and lie on the "motherboard" parallel to the board itself (for more details, see "Form factor"). Like most compact designs, thin mini-ITX boards do not have high processing power.
Note that most cases allow the installation of smaller motherboards — for example, many E-ATX cases can be used with ATX motherboards. However, specific compatibility anyway should be clarified separately.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.
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.
Liquid cooling (rear)
The size of the seat for the water cooling system provided on the back of the case.
In cases with CBO support, water cooling radiators are installed in the same slots as traditional fans. In other words, either a fan (fans) or a CBO radiator can be installed on the same seat. The size of the seat under the CBO is indicated by one number — the length (on the larger side); the width can be determined based on these data. The fact is that modern CBO 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 turns out to be 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.
Note that in this case, the same nuances are relevant as for air cooling: a larger fan takes up more space and costs more, but it is considered more advanced, as it can work efficiently at a lower speed — and this reduces the level of noise and vibration.
Liquid cooling (top)
The size of the seat for the water cooling system provided on the top side of the case.
In cases with CBO support, water cooling radiators are installed in the same slots as traditional fans. In other words, either a fan (fans) or a CBO radiator can be installed on the same seat. The size of the seat under the CBO is indicated by one number — the length (on the larger side); the width can be determined based on these data. The fact is that modern CBO 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 turns out to be 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. In general, the size of the upper radiator of
240 mm or less is considered relatively small, 280 mm — medium,
360 mm — large, and in some models it reaches
420 mm or even more.
Note that in this case, the same nuances are relevant as for air cooling: a larger fan takes up more space and costs more, but it is considered more advanced, as it can work efficiently at a lower speed — and this reduces the level of noise and vibration.
USB type C 3.2 gen1
Number of native
USB-C 3.2 gen1(previously USB-C 3.1 gen1 and USB-C 3.0) connectors provided in the chassis.
Such connectors are usually located on the front side (for more details, see "Location"). They are most convenient for peripherals that need to be connected and disconnected often — for example, "flash drives" (for permanently connected devices, it is more convenient to use motherboard connectors that are displayed on the rear panel) . Specifically, USB-C is a relatively new type of USB connector — smaller than classic USB and double-sided design. The use of such a connector may be different, depending on the features of the motherboard: in particular, it can also be used as a Thunderbolt v3 port, and the 3.2 gen1 connection interface is characterized by a bandwidth of up to 4.8 Gbps.
USB type C 3.2 gen2
Number of native
USB-C 3.2 gen2(previously USB-C 3.1 gen2 and USB-C 3.1) connectors provided in the chassis.
Such connectors are usually located on the front side (for more details, see "Location").

USB-C is a relatively new type of USB connector — smaller than classic USB and double-sided design. The use of such a connector may be different, depending on the features of the motherboard: in particular, it can also be used as a Thunderbolt v3 port, and the 3.2 gen2 connection interface is characterized by a bandwidth of up to 10 Gbps.
More features
—
Front cover. A hinged cover that completely or partially covers the front panel. Gives the computer a neat appearance, hiding connectors and external slots under a solid, uniform surface and performs the function of child protection.
—
Panel display. A display on the front or side panel of the case, used to display various service information: the current processor frequency, data on the system temperature, cooling operating mode, etc. Various important data can be displayed on the display without reference to what is happening in the software part of the computer.
—
Video card holder. A design solution for supporting a video card inside the case. Specialized stands or holders prevent the graphics adapter from sagging over time and reduce the load on the PCI-E slot of the motherboard. The fact is that many models of modern video cards have gained some weight - the holders are designed to compensate for their weight. Stands are available both as built-in solutions and as separate accessories that can be installed inside the case independently.
—
Side panel lock. The presence of a special lock on the removable side panel of the case. Such a lock prevents unauthorized access to the internal volume of the system unit.
—
Noise isolation. Availability at the case of
...additional sound insulation. This can be either a special coating on the inside, or other, more specific solutions (for example, damping systems on “seats” for individual components that reduce the level of vibrations transmitted to the body). Anyway, this feature helps to reduce the noise level emitted by the system — sometimes quite significantly.
— Removable basket for HDD. The presence in the design of the case of a removable basket for the inner periphery of the 3.5 "form factor (in the vast majority of cases these are hard drives, hence the name). Such a basket facilitates assembly due to the fact that it is much easier to remove it and install a hard drive inside than mount it in a non-removable compartment inside the case; this moment is especially useful if you plan to install several hard drives in the system.
— Docking station for HDD. Built-in docking station for quick connection of internal hard drives. In fact, this function allows you to connect an internal HDD as an external one: the docking station connector is located outside the case and is equipped with quick-release fasteners for easy connection.
— Concealed wiring. The ability to run wires from the power supply on the back of the motherboard (if we take the side where the processor and slots for expansion cards are located as the main one). Thus, the space on the main side of the "motherboard" is freed from wires, which, in particular, has a positive effect on the cooling efficiency.
— The window for installing the cooling system(Cooling system) for CPU. The presence of a separate window in the case opposite the CPU fasteners. The mounting system is located on the back of the motherboard, and usually, in order to change it, you need to remove the entire "motherboard"; the Cooling system installation window saves the user from such a need and greatly simplifies the installation and change of Cooling system.
