In order to select components for a computer, you must first determine the requirements for your device, which depend on the purpose of the PC and the features of working with it.
Office computer accessories
If you are looking for accessories for an ordinary office computer, you do not need to invest a lot in equipment. Working with documents, accounting, spreadsheets and other office programs does not require high computer power, so pay special attention to the reliability of the hard disk and power supply. A good hard drive is needed for storing information, and a high-quality power supply will ensure long-term uninterrupted operation during the working process. You can take the cheapest parts for other components. You probably won't need a floppy drive, but an additional USB hub will do the trick.
"Family" computer for home use
The time of tablet computers, laptops and smartphones has determined the trend of buying one personal computer for the whole family, in the memory of which shared files, films, photographs, etc. are stored. In addition, a stationary computer is usually a device for games, since it is much more convenient to play modern computer games on it than, for example, on a tablet. The large multimedia library of a home computer dictates the choice of a good graphics card as well as a quality sound card. Besides, you shouldn't skimp on RAM and processor power.
Gaming computer
If you can classify yourself as a gamer and cannot imagine life without games, then you need special PC components. First, it has to be a very powerful graphics card that will cost you half the cost of all the hardware. Secondly, you need a good processor and a lot of RAM. They usually do not spare money for such a computer, since modern games "put forward" quite high requirements to the PC.
Professional computer
A professional computer is usually required by those whose professional activities are related to programming, design, video editing, etc. The capabilities of an ordinary "family" PC are not enough to perform tasks such as 3D modeling, editing and launching complex programs. Therefore, it is necessary to pay special attention to the processor - it must have maximum power and a large amount of RAM. Also, to store "heavy" files, such as videos, you need a large hard drive.
