Board placement
The position of the motherboard in the case; it is assumed that the body is in its original position.
The motherboard is most conveniently placed along the case — this gives the most space for it (and "motherboards", we recall, are large in size). And since the most popular nowadays are vertical-layout cases (mainly certain types of “towers”), the boards in them are arranged vertically. The horizontal arrangement can be found much less frequently — in separate Mini-Towers and "cubes" (Cube Case), where the height is not much greater than the width, as well as desktops designed for horizontal placement.
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.
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.
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 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 (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.
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.
