Comparison Zalman ZM-T4 black vs Chieftec Compact IX-01B-OP black

The direction in which the body is facing. This parameter is indicated only for models that have a certain specialization and differ markedly from general-purpose cases.

— Gaming. Cases designed for high-performance gaming computer systems. They usually have numerous openings for expansion slots and bays for drives (see the corresponding paragraphs), as well as advanced options for installing cooling systems — many “seats” for fans, the ability to use liquid cooling (see “Liquid cooling support”) and etc. In addition, they often stand out due to their design: they can be equipped with decorative lighting, transparent windows, etc.

— HTPC. Enclosures for PC multimedia orientation, the so-called Home Theater Personal Computer (HTPC). The characteristic features of such cases are compact size, the presence of additional buttons on the front panel for controlling multimedia (and sometimes a sensor for the remote control) and an advanced design.

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 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.

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 form factor of the power supply that the chassis is designed to support. The form factor of the PSU is indicated by the type of motherboards for which the block was originally “sharpened”; however, many form factors are mutually compatible.

— ATX(regular). Form factor designed for full-size cases, mainly Tower and Desktop types (see "Form Factor"). The motherboard is powered by a 24-pin (in older versions — 20-pin) connector; in addition, such power supplies usually provide an additional power plug for CPU (4-pin, 8-pin, and sometimes both at once).

— FlexATX. The FlexATX form factor provides a miniature size of the motherboard (in terms of size and location of the mounting holes, such boards are compatible with microATX). Accordingly, the power supplies for them are compact in size and have increased efficiency characteristics. They are compatible with many miniature motherboards, including the mentioned microATX and mini-ITX, and the main connectors are the same as in ATX (minus the 20-pin version).

— TFX. The abbreviation TFX comes from Thin Form Factor — i.e. "thin form factor". This is one of the varieties of compact power supplies used in miniature form factors systems; similar in compatibility to the microATX described above, and in terms of connectors — ATX.

— SFX. Another type of po...wer supply with reduced dimensions, used in compact systems (S — from "small", i.e. "small"). In terms of connectors, it is considered completely interchangeable with ATX, it fundamentally differs only in size.

— External. Cases that do not have space for an internal power supply at all and are designed to connect an external power supply unit. This design is found mainly among the smallest cases (in particular, for mini-ITX and thin mini-ITX motherboards). Note that in this case, not every case with an external power supply is meant, but only models that do not have built-in converters (see below) and are designed for motherboards with their own connector for an external power supply.

— External with converter. Enclosures designed for external power supplies (see above) and equipped with built-in converters. The converter outputs power from an external PSU to a number of "computer" connectors, in particular, a standard 24-pin motherboard power connector. Thus, in such a case, you can install a "motherboard" that has a traditional "ATX" power supply in 24-pin format.

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 thickness of the side walls used in the case. When choosing a thickness, manufacturers have to compromise between several points at once. On the one hand, thin walls are inexpensive and heat dissipates faster through them, which has a positive effect on cooling efficiency. On the other hand, powerful systems inevitably require thick walls, otherwise the case may simply not withstand the weight of advanced high-performance components. Thirdly, steel is a fairly durable material even with a relatively small thickness. In light of all this, in most models this indicator does not exceed 0.7 — 0.8 mm, and more often it is about 0.5 – 0.6 mm.
