How to assemble a PC: The Case

If you are thinking of assembling a new computer from scratch, you want to upgrade your build, or you want to overturn your configuration, you should seriously consider the possibility of changing case.

In fact, the case is one of the fundamental elements in a configuration! First of all, it is the case of the various hardware components, including motherboard, processor, graphics card, power supply; its task is to protect the parts of the PC from dust and external factors, such as heat.

Therefore, not indifferent prerequisites when choosing a case are:

  • Airflow (the flow of air inside the case), which ensures an environment that is always fresh and clean by means of fans.
  • The dimensions, which depend on the internal components (if we choose a mATX motherboard, we can very well reduce the size of the case, on the contrary, if we use an ATX motherboard, we need a bigger case).
  • The amount of case, which allow us to insert more or less peripherals such as Hard Drives, SSD, DVD players or other.
  • The aesthetic factor, which depends on the user’s taste, which considers the color, the shape, the weight, or if it is a window.

After this brief introduction, let us enter into the merits of the question.

Assembly Rules

The case, which we said was the accommodation of all the components, has very simple assembly rules. In fact, assembled the block formed by the processor, RAM, GPU (optional) and motherboard, we insert it in the case. Once checked that the I/O panel (the one with the USB, HDMI, audio ports) exactly matches the recess space on the rear panel, screw the motherboard with the screws already in the package.

Then we also insert the power supply (usually in the lower left) by screwing the façade outwards that will allow us to turn the system on or off, and to connect the power cord. We use the wiring present in the package to feed the various components.

Placed the various disks (HDD, SSD) in their case, we connect via SATA the memories to the motherboard and the power-supply cable to the power supply.

As for the fans, simply screw them into the appropriate spaces and connect them to the motherboard.

Devices such as power button, reboot, USB ports and audio jacks have a separate discussion. We can observe that these must be connected to the motherboard in order to work. Usually, the place where you place the pins to which you connect the cables is at the bottom right of the board, where it says ” Panel “. By following the instructions provided by the motherboard in order, we will be able to connect all the peripherals in an optimal way.

The market offers a vast amount of case, each of which has its pros and cons, its own style, its size, its price. Let’s see what are, then, the best case by price range: low, medium and high.
