Comparison Gamemax H602 white vs Zalman ZM-T4 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 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.

The number of 5.25" form factor bays provided in the case design. Such bays are made only external, that is, they can be accessed from the outside without opening the case (unlike 3.5", see the corresponding glossary items). Today, 5.25" bays are mainly used for installing optical disk drives, internal hard drives in removable pocket adapters (Mobile Rack), and sometimes additional fans. Also, 3.5" devices can be installed in such bays using special adapters. ". Most cases are equipped with 1 5.25" bay or two bays. But there are models with 3 or more bays, as well as cases without external bays.

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 back 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; specifically for the rear panel, the size up to 92 mm is considered relatively small, 120 mm — medium, 140 mm — large.

Most often, the holes for installing fans are designed for one specific size, however, there are also “multi-size” seats, for 2-3 options in diameter.

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 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.
