Product type
The general type of computer. In addition to classic
desktop models (including
gaming purposes), more unusual solutions are also found nowadays:
monoblocks,
nettops,
microcomputers. Here are the features of each type:
— Desktop. Traditional desktop PCs, in other words, models that do not fit into any of the more specific categories. For the most part, they are not even desktop, but rather "below the table" — they are carried out in vertical cases, most often placed under the tabletop, horizontal system units are extremely rare among such devices.
— Game. A variety of desktop computers, designed for professional players and gamers-enthusiasts. Such models are necessarily equipped with a powerful hardware, which allows you to comfortably play even demanding modern games. In addition, they often provide various additional features that are useful for specialization: built-in overclocking tools, high-end customizable cooling systems, etc. Another feature of gaming PCs is a distinctive design, often quite original: in an “aggressive” style, with backlight, unusual body shape, transparent inserts, etc.
— Monoblock. Monoblocks are devices that combine a screen, system unit electronics, a set of connectors and acoustics in one case; in other words, these are monitors with built-in comp
...uter “hardware”. This design has two main advantages. Firstly, the system initially has a display, and it is quite large and optimally suited to its configuration — so the user does not need to look for a separate screen. Secondly, such a computer takes up very little space — only slightly more than a monitor with the same screen size; and the absence of a separate system unit can be written down as an advantage. On the other hand, if in a regular PC the “system unit” and the monitor can be selected separately, at your discretion, then in monoblocks this is not possible — you have to get by with the combinations that the manufacturer initially offers. In addition, the possibilities for modification and upgrade for such models are noticeably more modest than for traditional ones, and there is no talk of replacing the screen at all.
— Nettop. Devices also known as "mini PCs". They are small and modestly equipped — in particular, a very limited set of ports. In addition, many nettops do not differ in performance and are designed mainly for working with documents, surfing the Internet and other simple tasks. However, there are also quite powerful performant solutions. Anyway, the main advantage of the nettop is compactness.
— Microcomputer. As the name suggests, this type of computer is extremely tiny—comparable in size to a flash drive—and looks more like portable adapters for external screens than stand-alone devices. The case of such an “adapter” usually has its own HDMI connector, which is used to connect to a monitor or TV; the same port provides power. And the case most often provides for a “mobile” energy-saving processor with integrated graphics, a compact SSD or eMMC drive, and wireless modules. Peripherals like keyboards and mice are connected mainly via Bluetooth, but many models have wired connectors like USB, and sometimes in quite a decent amount (2 or even 3). In general, such a device can be a good alternative to a tablet or laptop for those who often move between different workplaces — the main thing is that these places have appropriate screens for connection. The power of microcomputers, naturally, is low, but they are not designed for "heavy" tasks.
— Thin client. Thin clients are computers designed to be used in terminal mode for external servers. In this case, all resource-intensive calculations are performed by the server, and the functions of the thin client are limited to entering initial data and receiving results. Most of these computers do not involve independent work at all, but this is not a drawback, but a feature of specialization. In general, this format of work is not used in everyday life and in the ordinary business sphere, but it is perfect for some highly professional tasks. And since the thin client does not need high performance, it can be made as compact, lightweight and inexpensive as possible.Form factor
The form factor of a computer case characterizes, first of all, the internal volume. Main PC Form Factors:
—
Midi Tower. A representative of the tower family (tower cases) of medium size — about 45 cm in height with a width of 15-20 cm, with the number of external bays from 2 to 4. Most popular for middle-class home PCs.
—
Mini Tower. The most compact "vertical" case type, with a width of 15-20 cm, has a height of about 35 cm and (usually) less than 2 compartments with external access. Used mainly for office PCs that do not require high performance.
—
Full Tower. The tower case is one of the largest form factors for PCs today: 15-20 cm wide, 50-60 cm high, with up to 10 externally accessible bays. Most often in this form factor running advanced high performance PCs
—
Desktop. Enclosures designed for installation directly on the desktop. They often have the possibility of horizontal installation — in such a way that a monitor can be placed on top of the case — although there are also models that are installed strictly vertically. Anyway, "desktop" models are relatively small.
—
Cube Case. Cases having a cubic or close to it shape. They can have different sizes and are intended for different types of motherboards, this point in each case should be clar
...ified separately. Anyway, such cases have a rather original appearance, different from traditional "towers" and "desktops".Model
The specific model of the processor installed in the PC, or rather, its index within its series (see "Processor"). The full model name consists of the series name and this index — for example, Intel Core i3 3220; knowing this name, you can find detailed information about the processor (characteristics, reviews, etc.) and determine how suitable it is for your purposes.
Drive capacity
The volume of the main drive supplied with the PC. For models with combined storages (for example, HDD+SSD, see "Drive type"), in this case, the main one is considered to be a more capacious hard drive; and if there are two HDDs in the kit, then they usually have the same capacity.
From a purely practical point of view, the more data the drive holds, the better. So the choice for this indicator rests mainly on the price: a larger capacity inevitably means a higher cost. In addition, we recall that SSD-modules in terms of gigabytes of capacity are much more expensive than hard drives; so you can only compare carriers of the same type by the combination of volume and cost.
As for the specific capacity, a volume of
250 GB or less in modern PCs can be found mainly among SSDs. Hard drives of this size are almost never found, for them a capacity
of 250 to 500 GB is still considered quite modest.
501 – 750 GB is a pretty good value for an SSD, and among them it is also mainly used.
751 GB — 1 TB is an impressive figure for an SSD and an average for hard drives,
1.5 – 2 TB is a very solid capacity even for an HDD. And a very high capacity —
more than 2 TB — paradoxically, is found even among pure SSDs: such drives are installed in high-end workstations, where speed
...is no less important than capacity.2nd drive capacity
The capacity of the optional storage installed in the PC.
This parameter is relevant primarily for configurations with different types of media. So, in HDD + SSD and HDD + eMMC bundles, the hard drive is considered the main drive, and this paragraph indicates the capacity of the solid-state module. In SSD + eMMC configurations, eMMC is considered the second drive — less capacious and performing an auxiliary function. There are PC models with two hard drives, but in such cases, the drives usually have the same volume, and it does not matter for them which one is considered the main one.
If we talk about specific numbers, then the volume
up to 128 GB can be considered relatively small, and
128 GB or more is solid. For more information on volumes in general, see "Drive Capacity" above.
Internal 2.5" compartments
The number of internal bays in the computer for components of the form factor 2.5 ". This form factor is popular, in particular, among SSD drives, as well as compact ("laptop") hard drives.
Paying attention to the number of internal 2.5" bays makes sense, first of all, if you purchase a configuration without drives or plan to upgrade your PC in the future. It is worth noting that it is recommended to install drives not in a row, but through one slot — for cooling efficiency; so that ideally the number of slots should be twice the number of devices installed.
USB 2.0
The number of full size
USB 2.0 connectors provided on the front of the PC.
USB is the most popular modern interface for connecting peripherals. And the number of connectors is, accordingly, the number of devices that can be simultaneously connected to the front panel without the use of splitters. Specifically, version 2.0 was the most popular some time ago, but now it is considered obsolete, it is gradually being replaced by more advanced standards like USB 3.0 (3.1 gen1). However, USB 2.0 capabilities (data transfer rates up to 480 Mbps) are still sufficient for many peripheral devices, from keyboards and mice to printers. So this standard is still far from completely disappearing, and some PCs may
have several of these ports on the front panel at once.
Separately, it is worth noting that similar connectors are most often available on the back of the case. However, the front panel is closer to the user, and the sockets on it are optimal for peripherals that need to be connected and disconnected frequently, such as flash drives.
LAN controller
Model of the LAN controller installed in the computer.
The LAN controller provides communication between the motherboard and the network port(s) of the PC. The model of this controller is indicated if it is a high-class module, designed for high communication quality and maximum lag reduction. Such capabilities are especially important for gaming systems used in online games.
Audiochip
The model of the audio chip (a module for processing and outputting sound) installed in the computer. Data on the exact name of the sound chip will be useful when looking for detailed information about it.
Modern PCs can be equipped with fairly advanced audio modules, with support for high-quality sound and extensive features. Thanks to this, some configurations can even be used for recording and other professional audio work. However, if you are planning such an application, it would not hurt to clarify the specific capabilities of the audio chip separately: it may well be that even an advanced workstation will still need an external audio card.
