Comparison NZXT H9 Flow black vs NZXT H9 Elite black

The material from which the body is made.

— Steel. Steel cases are durable, scratch resistant, and relatively inexpensive. They are quite heavy, but given that most PCs are not designed to be frequently carried from place to place, this point can hardly be called critical. Due to this, this material is used in the vast majority of modern cases of all types, specializations and price categories.

— Aluminium. Aluminium cases are lightweight, provide improved heat exchange with the environment and are mostly stylish in appearance, but are more expensive and susceptible to scratches than steel. They are designed mainly for mid-range and top-end systems, where the cost of the case is negligible compared to the price of components, and the above-mentioned advantages are of decisive importance.

- Tempered glass. In this case, we mean cases made of glass panels mounted on a metal frame, most often steel. And the panels themselves are not necessarily all made of glass: at least the top and bottom are usually made of an opaque material, most often the same metal. In general, such cases are among the design solutions created based on the original appearance: they look really interesting, which is very much appreciated by modding fans. At the same time, from a practical point of view, glass has no advantages over metal, rather, on the contrary: this mate...rial is quite fragile and requires careful handling, but is not cheap.

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 ability to install a graphics card in the case vertically, facing the side panel. To do this, the design provides for an appropriate bracket, and the graphics card is connected to the motherboard with a special extension cable — a riser. This feature is found in open cases and models with a viewing window (see relevant paragraphs), its purpose is primarily aesthetic: a vertically placed graphics card is clearly visible from the outside, which gives the case an original appearance, designed for fans of external modding. But vertical installation does not provide any fundamental practical advantages.

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.
