If you don't want to buy a gaming PC from the Internet or an electronics shop, you still have the option of assembling a gaming PC yourself. But laymen often find it difficult to choose the right components. For this reason, we would like to show in the following article which components are necessary for a self-assembled gaming PC and provide suitable suggestions for the respective components.
In addition to our suggestions, you can also put together your own gaming PC in Alternate's practical configurator.
The right gaming PC case
A gaming PC case gives your computer an appealing look that also makes a good impression on friends and relatives. Glazed side windows, fans that are visible from the outside and, above all, colourful LED lights give a gaming PC case a special look.

But you shouldn't just buy any PC case, not just for its looks, but also for its function. A particularly important function of the case is its ventilation, or the cooling of the components installed in it. Components such as graphics cards, CPUs or RAM generate a lot of waste heat, especially when they are particularly powerful.
Even when installing several components of the same type, for example two graphics cards, you should always keep their heat emission in mind. If too much heat accumulates, the components could be damaged and their performance reduced, or you could get graphics errors or bluescreens.
To prevent the case from getting too hot, you should not choose a model that is too small and cram the components in wildly, but plan for sufficient space. Many gaming PC cases also have built-in fans that ensure the necessary dissipation of warm air. We have written a separate blog article for the best gaming PC cases 2018, in which some models are presented that already have built-in fans.
Also important: The enclosure should be aligned with the mainboard's design. There are different sizes to purchase here. The most common type is ATX, which is used in most home PCs. There are also smaller types such as microATX or MiniATX. Larger models are rare. It is important that the mainboard can be mounted correctly in the case, i.e. that the drill holes are the right distance apart.
Finally, you should take a look at the hard drive bays. If you want to retrofit several hard drives, you should make sure that they are the right size (2.5 inch or 3.5 inch) and that the gaming PC case offers the possibility or space to install additional hard drives.
The right mainboard
The mainboard (or motherboard) serves as the central connection point for almost all components of a computer. For example, the CPU (the "processor") is mounted on it, and it also offers a few other connections, for example for the mouse or the boxes.
There are two main factors to consider when choosing a mainboard: on the one hand, the chipset, which provides information about the features of the mainboard. And on the other hand, the socket of the mainboard on which the processor is placed. Intel and AMD each offer their own processor sockets, which also only fit their own processors. While Intel offers the two series LGA1151 (or LGA1151v2) and LGA2066, AMD's mainboard sockets are called AM4 and TR4.
The chipset roughly corresponds to the "equipment package" of a mainboard. This means above all: how many and which connections does the board have to offer? This includes, for example, the number of PCI slots required for the graphics card(s). In addition, attention is paid, for example, to various USB ports, interfaces for data exchange, the number of RAM slots, but also to heat sinks for the motherboard.
As already mentioned above, you should also pay attention to the size when choosing a motherboard so that it fits into the selected gaming PC case.
The right gaming PC processor
The processor is one of the most important components of any (gaming) PC and therefore deserves special attention. The processor is also called CPU (Central Processing Unit) and takes over the computing processes of a computer or the programmes running on it, regardless of whether you are gaming, working or watching a film with it.
When it comes to processors, there are really only two manufacturers worth mentioning: Intel and AMD. Both offer CPUs in all price and performance classes. Starting with the entry-level models (Core i3 at Intel, RYZEN 3 at AMD), the mid-range models (Core i5 at Intel, RYZEN 5 at AMD) and the upper-range models (Core i7 at Intel, RYZEN 7 at AMD) to the high-end models (Core i9 at Intel, RYZEN Threadripper at AMD), there is something for every demand and every budget.
It is important to note that these classifications have partly been valid for many years and there are several generations of, for example, Intel Core i5 processors. So just because you buy an i5 processor doesn't mean you have the latest model in your hand. Which manufacturer is better, by the way, has been the subject of discussions among gamers for years; there is no clear favourite.
When buying CPUs, two things play a decisive role: the number of cores and the processor's computing speed, measured in gigahertz (GHz). Common for current processors are 4,6, or 8 cores. The more cores and the higher the clock speed (the speed at which the cores work), the more powerful the processor. In addition, newer processors are of course usually more powerful than those of the older generation.
The socket size on your mainboard is also important when buying. Not every processor fits on every mainboard. The socket size must match the size of the processor.
