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.
Lighting sync
The timing technology provided in the illuminated housing (see “Light Type”).
Synchronization itself allows you to "match" the backlight of the case with the backlight of other system components — the motherboard, graphics card, keyboard, mouse, etc. Thanks to this matching, all components can change colour synchronously, turn on / off at the same time, etc. It is worth noting that all such systems have
RGB backlighting. The specific features of the operation of such a backlight depend on the synchronization technology used, and, usually, each manufacturer has its own (Mystic Light Sync for MSI, Aura Sync for Asus, etc.). The compatibility of the components also depends on this: they must all support the same technology. So the easiest way to achieve backlight compatibility is to collect components from the same manufacturer.
internal 2.5" compartments
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.
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.
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.
USB 2.0
The number of native
USB 2.0 connectors provided in the case.
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 the motherboard connectors displayed on the rear panel). Specifically, USB 2.0 is now considered obsolete: it provides a data transfer rate of only 480 Mbps and a relatively low power supply. However, in many cases this is enough, and USB 2.0 ports continue to be used, including in fairly advanced cases.
USB 3.2 gen1
The number of native USB 3.2 gen1 connectors (previously labeled as USB 3.1 gen1 and
USB 3.0) provided in the case.
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 the motherboard connectors displayed on the rear panel). Specifically, the USB 3.2 gen1 standard has replaced the USB 2.0 described above, it provides 10 times the data transfer rate (up to 4.8 Gbps) and higher power supply, while USB 2.0 peripherals can also be connected to such connectors .
It is worth remembering that for normal operation of ports, their number and version must correspond to the capabilities of the motherboard.
