Comparison Fractal Design Focus G black vs Zalman Z3 black

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 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.

For more on decorative lighting in general, see Light Type above. Here we note that it can have different shades, and sometimes several options are indicated in the characteristics at once. If these options are listed through "and" (for example, "red, blue and green") — this means that this model contains all the specified colours, and the user can switch between them at his discretion. If the shades are listed through “or” (for example, “red, blue or green”), this means that this model is available in several versions that differ in the colour of the backlight.

Special mention is the "RGB" option. This is the name of the most advanced backlight, the shade of which can be chosen at your discretion. However the original RGB backlighting is capable of simultaneously displaying only one of several basic colours (white, yellow, green, red, blue or purple); nevertheless, even these possibilities are enough to customize the appearance of the case and apply various effects (such as backlight synchronization — see below).

And relatively recently, an even more advanced type of adjustable systems has appeared — ARGB backlight. The key difference between ARGB and classic RGB is the possibility of simultaneous operation of diodes of different colours. In other words, classic RGB lighting can display only one colour at a time, while ARGB can display several colours, which provides additional effects. Also, ARGB lighting is connecte...d using a 3pin 5v connector, while regular RGB uses a 4pin 12v connection. It can be represented by various types of illumination. So, ARGB is often integrated into the cooling system, the front panel and magnetic LED strips, which the user can mount at his discretion. To control the backlight, a special controller is usually provided, and buttons or controls for switching the illumination operation modes are placed on the interface panel. In some cases, the backlight is controlled by the motherboard, through a special connector. Many ARGB systems support the ability to fine-tune through specialized software.

The number of external 3.5" component bays provided in the case. The name "external" means that the bay has an exit to the outside (usually to the front panel), and can be reached without opening the case. One of the most popular options the use of such slots — the installation of card readers; in addition, they can be used for other components — in particular, USB hubs.

The number of bays corresponds to the number of external components that can be simultaneously installed in the case. However, this form factor is not particularly popular in the outer periphery, so cases with more than 2 such compartments are rare.

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.

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.

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.

The number of fan slots on the top side 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, 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 chosen size: for example, there are gaming cases where you can install either one 180 mm fan or four 120 mm fans at once.
