The system unit is the center of the entire computer. It contains the components responsible for its performance. However, a complete update of the system unit is often required to maintain the characteristics of the computer up to date.
Instructions
Step 1
There are two options for purchasing a new system unit. The first is a choice from already assembled system units, the second is the purchase of all components separately for subsequent assembly. Choose the option that suits you best.
Step 2
When choosing a ready-made system unit, carefully study all its characteristics: processor power, amount of RAM, hard disk capacity, video card power and sound card quality. Pay special attention to the presence of additional interfaces, devices and their characteristics. For example, the number and location of usb ports, the presence of a network card, wi-fi adapter, etc. They are an important component of the system unit's functionality, but some of them (for example, a card reader, wi-fi or bluetooth antenna) may not be necessary for someone.
Step 3
Sometimes a ready-made system unit is sold with a pre-installed operating system, respectively, the fee for it is included in the total price. If you already have a purchased copy of the operating system or you are going to use a freely distributed one, purchasing such a system unit will entail unnecessary expenses.
Step 4
If you could not find a suitable ready-made system unit, assemble it piece by piece. Separately select the motherboard, processor, RAM, hard drive, video and sound card, other devices are optional. If you do not have enough experience in this matter, consult with the seller about the compatibility of the components. Thus, you will buy exactly such a system unit that will suit you in terms of functionality.
Step 5
If you are going to buy a used system unit, check the ads in the relevant sections of newspapers, forums and message boards on the Internet. If you have a suitable option, contact the owner and make an appointment. Carefully check the functionality of the system unit before purchasing.
