Comparison Cougar QBX black vs Cooler Master Elite 130 black

The form factor determines, first of all, the internal volume of the case (as a result, the motherboard used for it, see "Type of motherboard"), as well as installation features. To date, PC cases are available in the following main form factors:

— Full Tower. The tower case is one of the largest form factors for PCs today: 15-20 cm wide, 50-60 cm high, with up to 10 externally accessible bays. Most often in this form factor running advanced high performance PCs.

— Ultra Tower. Further development and expansion of Full Tower cases (see above), offering even more space for hardware: the width of such a case is about 25 cm, the height can reach 70 cm, which allows you to install powerful configurations inside and provides enough free space for effective cooling .

— Midi Tower. A representative of the tower family (tower cases) of medium size — about 45 cm in height with a width of 15-20 cm, with the number of external bays from 2 to 4. Most popular for middle-class home PCs.

— Mini Tower. The most compact "vertical" case type, with a width of 15-20 cm, has a height of about 35 cm and (usually) less than 2 compartments with external access. It is mainly used for assembling office PCs that do not require high performance.

— Desktop. Enclosures designed for i...nstallation directly on the desktop. They often have the possibility of horizontal installation — in such a way that a monitor can be placed on top of the case — although there are also models that are installed strictly vertically. The size of such cases can be almost anything — from miniature solutions for thin mini ITX motherboards to large-sized cases for E-ATX (see "Motherboard type"). However, most "desktops" are relatively small.

— Cube Case. Cases having a cubic or close to it shape. They can have different sizes and are intended for different types of motherboards, this point in each case should be clarified separately. Anyway, such cases have a rather original appearance, different from traditional "towers" and "desktops".

— Dual Tower. Quite a rare option — cases, in size and proportions resembling two "towers", made up side by side. Dual Tower solutions are large in size and are intended mainly for powerful high-performance PCs (in particular, top gaming stations).

Note that there are models that allow both vertical and horizontal installation and can, in fact, turn from a "tower" to a "desktop" and vice versa. For such cases, the form factor is indicated by the form factor named in the manufacturer's documentation, or by the main installation method described there.

Mounting method, nominally assumed by the body design.

— Vertical. Enclosures of this type, when installed, take up much more space in height than in width. This option is standard for all Towers (see "Form Factor"). It is convenient in that it requires relatively little free space on the floor or other support for installation. Many of these cases are designed primarily for floor or similar placement (for example, in a special compartment of a computer desk, under the table top), although there are other options — desktop installation and even mounting on the back of a monitor.

— Horizontal. Cases arranged horizontally. This is the standard installation method for most "desktops" (see "Form Factor"). Actually, such a layout is convenient just when placing a computer on a table — in particular, the monitor can be placed directly on the case, or, in some cases, next to the case.

— Vertical and horizontal. Universal housings that can be placed both vertically and horizontally, depending on specific conditions. This eliminates the hassle of installation to a certain extent — the universal model can be adjusted to the characteristics of any workplace. At the same time, this option is found both among miniature cases and among full-size ones.

Note that although purely technically installing the case in a “non-native” way (for example, v...ertically on its side) is not particularly difficult, it is still not recommended to do this. After all, the design itself was initially optimized for one or another situation — suffice it to say that this is connected, in particular, with the efficiency of cooling systems.

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.

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.

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.

The presence of rubberized legs in the design of the case.

These feet absorb vibrations generated during operation of the computer (mainly due to the operation of fans and optical drives), thereby reducing noise levels and providing additional comfort. Rubberized feet are especially desirable if the computer is placed on a table (on a tabletop or in a dedicated compartment on a table) or on a hard floor.

— Removable panel. Opening by removing one or more panels is the most popular option in modern PC cases. This design is inexpensive, convenient and practical, and fits any form factor (see above). The specific device of such an opening system just depends primarily on the form factor, more precisely, on the overall layout of the case. So, in vertical products (one or another type of Tower), both side panels are usually removable, in horizontal “desktops” — the top panel, and in the Cube Case the options may be different.

— U-shaped cover. A solid cover of a characteristic shape — in the form of the letter "P" — covering the case simultaneously from the sides and from above. Thus, when such a cover is removed, the case is open from three sides at once. In some cases (for example, to access the top 5.25" compartment, this feature turns out to be very useful. At the same time, U-shaped covers are rather bulky, removing and putting such a part in place is noticeably more difficult than carrying out these operations with separate removable panels; this is especially true for vertical tower cases, which is why this opening mechanism is rare these days, almost exclusively in Desktop and CubeCase products.

— Door. Another rather rare opening mechanism, in this case, typical for cases in various variations of the Tower form factor. The name quite accurately conveys the way this mechanism works: the side panel of the case is not...removed, but opens sideways like a hinged door. The main advantage of this option is that a convenient lock is often used to fix the door in the closed position, which can be opened without special tools — for example, by pressing a button. This greatly simplifies access to the contents of the case, especially when you need to fine-tune or quickly replace individual PC components. On the other hand, the open door cannot be set aside like a removable panel, and in some situations it can be inconvenient by hanging on the case. Yes, and such a design is somewhat more expensive than the same removable elements. Therefore, doors are rarely found nowadays — mainly in separate game models of cases (see "In the direction").

The number of 5.25" form factor bays provided in the case design. Such bays are made only external, that is, they can be accessed from the outside without opening the case (unlike 3.5", see the corresponding glossary items). Today, 5.25" bays are mainly used for installing optical disk drives, internal hard drives in removable pocket adapters (Mobile Rack), and sometimes additional fans. Also, 3.5" devices can be installed in such bays using special adapters. ". Most cases are equipped with 1 5.25" bay or two bays. But there are models with 3 or more bays, as well as cases without external bays.

The number of internal 3.5" form factor bays provided in the design of the case. Such bays, in accordance with the name, are intended for internal components, mainly hard drives and some SSD modules; to access them, the case must be disassembled.

Theoretically, the number of bays corresponds to the maximum number of drives that can be installed in the chassis. However, in fact, the best option is to install drives through a single slot to ensure efficient cooling. Accordingly, it is best to select a case in such a way that the number of internal 3.5" bays is twice the expected number of hard drives.
