Comparison Xigmatek Astro black vs Xigmatek Astro A black

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 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.

This feature is indicated for housings that normally allow the installation of liquid cooling systems(LCS). Such systems are extremely efficient, but complex and expensive, so they are mainly used in high-performance PCs, for which traditional coolers are no longer enough. Note that theoretically, liquid cooling can be installed in almost any case; however, if support for such cooling is not initially provided in the design, this can be very difficult. So if you initially plan to use LSS, you should choose a case for which support for this function is directly claimed.

Size of the mounting space for the liquid cooling system provided on the back of the case.

In cases supporting liquid cooling systems, water cooling radiators are installed in the same slots as traditional fans. In other words, either a fan (or fans) or a liquid cooling radiator can be fitted into the same space. The size of the mounting space for a liquid cooling system is indicated by a single digit — the length (on the larger side); the width can be determined based on this information. The point is that modern liquid cooling radiators typically use fans of one of the standard sizes — 120 mm or 140 mm; and if there are several of such fans, they are arranged in a row. As a result, the length of the radiator becomes a multiple, and the width is equal to one of these numbers: for example, 280 mm is 2x140 mm with a width of 140 mm, and 360 mm is 3x120 mm with a width of 120 mm.

Note that the same nuances are relevant here as for air cooling: a larger fan occupies more space and is more expensive, but it is considered more advanced as it can operate efficiently at lower speeds — which reduces noise levels and vibrations.

The size of the mounting space for the liquid cooling system provided on the front side of the case. In cases with support for LCS, water-cooling radiators are installed in the same slots as traditional fans. In other words, either a fan (or fans) or an LCS radiator can be installed in the same mounting space. The size of the mounting space for LCS is specified by a single number — the length (on the longer side); the width can be determined based on these data. The fact is that modern LCS radiators usually use fans of one of the standard sizes — either 120 mm or 140 mm; and if there are several such fans, they are arranged in a row. As a result, the radiator length is a multiple, and the width is equal to one of these numbers: for example, 280 mm is 2x140 mm with a width of 140 mm, and 360 mm is 3x120 mm with a width of 120 mm. Generally, a front radiator size of 240 mm or less is considered relatively small, 280 mm is medium, 360 mm is large, and in some models, it reaches 420 mm and even 480 mm. Note that the same nuances apply here as for air cooling: a larger fan occupies more space and costs more, but it is considered more advanced because it can work efficiently at a lower speed — reducing noise and vibrations.

The size of the mounting space for the liquid cooling system provided on the top side of the case.

In cases supporting LCS, water cooling radiators are installed in the same slots as traditional fans. In other words, a fan (or fans) or an LCS radiator can be installed in the same mounting space. The size of the mounting space for LCS is specified by a single number — the length (on the longer side); the width can be determined based on this information. The fact is, modern LCS radiators typically use fans of one of the standard sizes — 120 mm or 140 mm; and if there are several such fans, they are arranged in a row. As a result, the length of the radiator is a multiple, and the width is equal to one of these numbers: for example, 280 mm means 2x140 mm with a width of 140 mm, and 360 mm means 3x120 mm with a width of 120 mm. Overall, an upper radiator size of 240 mm and below is considered relatively small, 280 mm is medium, 360 mm is large, and in some models, it reaches 420 mm and even 480 mm.

Note that the same nuances apply here as for air cooling: a larger fan takes up more space and costs more, but is considered more advanced since it can work effectively at a lower speed — which reduces noise and vibrations.

The total number of spaces available for liquid cooling systems in the case, in other words, the maximum number of LCS radiators that can be installed in the case. These radiators are usually placed one per side of the case, so several radiators are often located on different sides: for example, 3 LCS spaces can be located at the rear, top, and front.

When evaluating the number of mounting slots (of all types), it's important to consider that fans and LCS radiators usually use the same mounting locations.
