Comparison Zalman Z3 black vs Zalman Z3 Plus black

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.

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 more fans are included in the design, all else being equal — the more intense the cooling will be and the more powerful (and, consequently, "hotter") components can be placed in the case without the risk of overheating. For everyday tasks, a case with one, two, three, or four factory fans is quite sufficient. At the same time, when comparing, it is worth considering not only the number but also the operating characteristics of the fans (diameter, speed). It should also be noted that cases are available for purchase without fans but with open slots for fans, allowing you to supplement the cooling system and improve its performance if necessary.

The presence of a viewing window on the side panel of the case, allowing you to see the “filling” without opening the case. It gives the case a stylish appearance; in addition, it allows you to install a lighting system inside, which is appreciated by gamers compared to case models without a window.

The materials for manufacturing the windows on the side panel are:

- Acrylic. Acrylic or plexiglass is an inexpensive material of relatively light weight, which, however, actively collects scratches and can be deformed when exposed to high temperatures.

- Strained glass. Tempered glass panels have excellent transparency, are resistant to scratches and are easy to clean from dirt. At the same time, they weigh a lot and can break to pieces if not handled carefully.

- Metal grid. Wire mesh is a simple type of window material used on the side panel of a cabinet. It allows air to pass through and provides additional heat removal from the internal components of the system unit; dust can leak through the mesh overnight.
