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.
Integrated hub
A hub in a computer case for connecting fan and backlight control systems. Depending on the implementation, the
complete hub can be installed inside the case or placed on its outer panel. Often, a remote control with an infrared transmitter is attached to the hub to control the "turntables" and decorative lighting of the "insides" of the case.
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.
