Comparison Aerocool Aero-300 FAW black vs Zalman R1

The direction in which the body is facing. This parameter is indicated only for models that have a certain specialization and differ markedly from general-purpose cases.

— Gaming. Cases designed for high-performance gaming computer systems. They usually have numerous openings for expansion slots and bays for drives (see the corresponding paragraphs), as well as advanced options for installing cooling systems — many “seats” for fans, the ability to use liquid cooling (see “Liquid cooling support”) and etc. In addition, they often stand out due to their design: they can be equipped with decorative lighting, transparent windows, etc.

— HTPC. Enclosures for PC multimedia orientation, the so-called Home Theater Personal Computer (HTPC). The characteristic features of such cases are compact size, the presence of additional buttons on the front panel for controlling multimedia (and sometimes a sensor for the remote control) and an advanced design.

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 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 external 3.5" component bays provided in the case. The name "external" means that the bay has an exit to the outside (usually to the front panel), and can be reached without opening the case. One of the most popular options the use of such slots — the installation of card readers; in addition, they can be used for other components — in particular, USB hubs.

The number of bays corresponds to the number of external components that can be simultaneously installed in the case. However, this form factor is not particularly popular in the outer periphery, so cases with more than 2 such compartments are rare.

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 more fans provided in the design, other things being equal, the more intense the cooling will be and the more powerful (and, accordingly, “hot”) hardware can be placed in the case without the risk of overheating. For everyday tasks, a case with one, two or three factory fans is enough. At the same time, when comparing, it is worth considering not only the number, but also the performance characteristics of the fans (diameter, speed). Also note that there are cases without fans on the market with free space for fans, which allows, if necessary, to supplement the cooling system and improve its performance.
