How are computer housings made

PC case - an overview

The PC case is much more than a mere storage place for the hardware and should be chosen carefully. But what is important when making a purchase? Which housing types are there and what role does the form factor play in this? This page gives you an overview of everything to do with the computer case.


The PC case - more than just a storage place

A PC case does not only consist of four (side) walls and a roof. It is a comprehensive structure that holds the computer together and gives it its shape. The housing protects the entire electronic inner workings of the PC from external influences such as liquids, dust, dirt and the like. Inside the PC case there are various inlets, slots and openings that specify where the individual computer components can be attached. In some cases there is already a power adapter and one or more Fan built-in.

The power supply unit is inserted at the top or at the bottom; in modern towers, replaceable ones are available ex works Dust protection filter built in to protect the fan of the power supply unit from dirt. In the common housings are often Mounts in which you can install additional filters or fans, because depending on the performance of the PC, the integrated power supply fan is no longer sufficient for cooling and additional components must be installed. All components that develop heat during use must be cooled: Drives develop heat through the mechanical components, but the CPU (processor) or graphics cards also radiate heat and should be cooled. To do this, small fans are placed on the walls of the housing and the heat from the radiators is directed outside.

What you should also pay attention to when buying a housing are sufficient Interfaceson the front side. In previous cases, USB interfaces were only found on the back, but since almost everything works via USB these days, these are found on the front of the case. The same applies to memory card readers or audio input and output. The main board and plug-in cards (e.g. graphics card and sound card) are attached to the corresponding openings on the wide rear wall.

If you want to use water cooling for your computer, you will also find the corresponding feed on the back. High quality devices often have one Double wallbehind which the cables to the mainboard are routed. As a result, the inner workings are clearer and components can be replaced more quickly. In the housings there are mostly multiple bays for optical drives and hard drives / SSDs and some have special "hard drive cages" which have the advantage that several hard drives can be removed at once without having to remove them individually.

PC cases come in different sizes and designs which are standardized according to certain form factors (ATX and Mini-ITX are widespread). The designs are divided into big towers, midi towers and desktop PCs.

Note the form factor

Before buying a computer case, it is important to understand the different form factors and case types. In addition to the size differences that are quite easily recognizable from the outside, a case is also defined by the case form factor. You can guess this from the outside, but it is mainly relevant for the inner workings. Learn more about the form factor.


Which type of case should it be?

Would you like to assemble a new PC system on your own and are not yet sure what size your future case should be? Then you have come to the right place on this page!
Here you can find out more about the different housing types and get to know their advantages and disadvantages better.



Housing cooling - the way to the silent system

Your new PC shouldn't make any annoying noises while gaming or working? Then you should take a closer look at the case cooling before buying. But even if you are not bothered by fan noise, it is important when assembling a PC that the cooling system used is optimally matched to its performance. Find out here how you can reliably cool your case.
