Comparison DarkFlash C285P black vs Gamemax Infinity 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 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 location of the power supply (or seat for the power supply) in the case.

The traditional option is the top location of the PSU, this is a familiar and familiar option for many. However, heated air from other system components accumulates in the top of the case, reducing cooling efficiency. Cases with a lower location of the PSU are deprived of this drawback, however, a lot of dust and other contaminants get into them if the system unit is installed on the floor. However, this difference becomes critical only when using high-performance systems with appropriate heat dissipation; for an ordinary household PC, the location of the power supply unit as a whole is not important.

Also note that in miniature cases like mini-Tower (see "Form factor"), the PSU installed on top can overlap part of the motherboard, which further worsens the cooling efficiency and makes it difficult to install large CPU coolers; however, it all depends on the layout of a particular case.

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 number of internal 2.5" bays provided in the case design.

Such bays are mainly used for installing internal hard drives and SSD modules; The 2.5" form factor was originally created as "laptop" form factor, but recently it has been increasingly used in components for full-size PCs. At the same time, when evaluating the number of these bays, note that drives are recommended to be installed through a slot; so in Ideally, the number of bays should be twice the planned number of drives.

Also note that some cases use combined bays: initially they have a size of 3.5", but if desired, they can be converted to 2.5". These bays count towards both 3.5-inch and 2.5-inch slots. In fact, this means that the total number of available slots is not always equal to the sum of the number of both. For example, a case with 10 3.5" bays and 6 2.5" bays can have 4 combined bays, and the total number of slots in this case will not be 16, but only 12.

The number of fan slots on the sides of the case, as well as the size of the fans that 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 for 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.

The total number of places for installing fans provided in the chassis design.

The more performant the system, the more components it includes — the more powerful cooling it will need; therefore, the number of places for fans, usually, is directly related to the size and purpose of the case. It is also worth considering that with the same number, the installation location of individual fans may be different — behind, on the side, on top, etc.

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.
