Is it difficult to get a PC
to put together yourself?

Have you ever played with the idea of building your own PC? But you haven’t dared so far because you think it would be too difficult?

I’ll tell you what you should know if you want to build your own computer. Among other things, you’ll find out which parts you should never do without, what the most common assembly mistakes are and what you should definitely stay away from.

Does a self-built PC have advantages?

Mostly the first question is, if there are advantages to build your own PC and assemble it yourself. After all, it is very convenient to just go to a store and buy a ready-made device.

And after all, there is a colorful selection of models, so that actually every user can find a calculator that he likes. Still, there are some distinct advantages to building your own PC.

The financial screw

A big advantage of the self-made PC is the money factor. You can decide for yourself which components you absolutely want to have and which things you can comfortably do without.

For example, if you want a gaming computer, speed and a good graphics card are important. But if you want to use your computer more for surfing the web or watching movies, other factors are more important.

You can plan in advance exactly which components your PC should have later and how much money you want to spend on them.

Accordingly, you can realize the dream of your own computer even with a rather small purse and do not have to spend several thousand euros.


When you buy a ready-made computer, you simply have to take what you get. Mostly it means that you have no influence on what components are installed or what programs are pre-installed.

As a result, you may spend a lot of time deleting annoying memory hogs before you can really use your computer.

On the other hand, if you assemble the PC yourself, you have direct influence on even the smallest screw. You can decide yourself how big the case should be and how many fans you want to install.

You can choose whether you want active cooling or passive cooling and what kind of hard drives you want to use.

Simple retrofitting

The best part is that you can always customize your PC to fit your needs. If you need more memory, it’s easier to upgrade because you know exactly what you have installed and what you need.

With a ready-bought computer you have to search for such information in some cases, if you don’t want to make a bad purchase.

What do I need for the assembly?

Tools pc assembly

If you want to build your own computer, then there are a number of components that you should not do without. But first, let’s take a look at what tools you should have on hand.

Work surface

You’re going to need room to put your PC together. Above all, make sure that the surface is stable and clean so that you can get started.

Screwdrivers in various sizes and designs

Screwdrivers are your all-purpose weapon. There is hardly a component that you don’t have to tighten in some way.

Cable tie

Order is half the battle – even in your own PC. Especially when replacing new components, you’ll be grateful if you don’t have to fight your way through a jungle of cables, but instead move past just a few bundles of cables. Here are more tips for good cable management.

Container for small parts

A screw can easily get lost in the hustle and bustle. To make sure that doesn’t happen, you should set aside a bowl or two to put all the small items in. This will make it much easier for you to assemble.


Think of a handy flashlight, smartphone, or other light source. You will need them if you want to connect, tighten and join all the parts correctly.


These PC components should not be missing in any case!

After the most common tools, we now come to the actually more exciting things. Here is your “shopping list” of components that should not be missing in a PC brand self-built in any case:

The housing

The case does not only decide how your computer will look like later, but also how much space you have to install it. As a layman, you should stick to enclosed cases with good ventilation options. Later you can also dare a housing with a viewing window, if you like.

The power supply unit

Your PC will need power. It receives this via the power supply unit. Here the one or other euro more is worthwhile itself, so that your PC works later on the one hand quietly and on the other hand remains efficient for a long time.

The mainboard

The mainboard or “motherboard” is the motherboard. All components are connected here.

The processor

The CPU is the brain of your future computer. When making the right choice, you should pay attention to whether the motherboard supports processors from AMD or from Intel. You can find this information in the manual of the motherboard.

Working memory

Memory or RAM is a sticking point for many games or programs. More RAM also means that, for example, images can be built up faster or your clicks are implemented more quickly by the PC.

The graphics card

The graphics card is the busy beast in your computer. It needs to quickly build, render and smoothly play back images and videos. Many games have high demands on the graphics card. Therefore, you should check in advance whether certain games or programs require a graphics card model as a system requirement. Benchmarks are a good way to do this.

Storage media

A hard disk is an absolute must for every PC. Data and programs have to be stored somewhere. It’s best to consider if you like normal HDDs or if you want to invest a little more money for a faster SDD .


Without proper cooling, your PC will quickly go to its knees. Each component contains sensitive electronics and will run hot quickly. To prevent this, you have the choice between active or fan cooling, passive plug-in cooling or water cooling. As a beginner you are better off with a fan because it is easy to install.

DVD drive

Even though CDs and DVDs are not that important anymore and you can download many programs from the internet, especially for the setup phase a DVD drive is worth its weight in gold to install your operating system and set up drivers.

Network card

Your gateway to the wide world of datais a network card. No matter if you want to surf with a cable connection or if you prefer to go wireless, you should not do without a connection to theInternet. Alternatively, there are also WLAN sticks that can be plugged into the PC from the outside.

Monitor and peripherals

Anything you don’t build into your computer is called a “peripheral”. This includes the monitor, mouse, keyboard, speakers, and maybe a controller.

What are the most common sources of errors and dangers when assembling?

pc assemble error

When assembling, it can of course happen that you break something or set a handle incorrectly. After all, it involves a large number of small electrical parts that are to form a finished PC in the end. I’ll introduce you to common hazards so you can wisely avoid them in your homebrew.

Working with electricity

When you are tinkering with your computer it is incredibly important that you unplug the machine. Otherwise, you run the risk of accidentally starting the device while you have your fingers inside.

However, a sudden power surge can also damage the built-in electronics and literally short-circuit the PC. Therefore: Disconnect the cable before you open the computer!

Raw forces

It is not necessary that you force your components in somewhere or press them down with force. Most of the time, light pressure is all that is needed to get the pieces in place. But if you press too hard on the parts, they can break easily and get broken.

rough edges

Your PC is full of sharp corners and some edges. It can easily happen that you scratch your fingers. Keep some Band-Aids handy just to be safe.

Unstable system

Not every part goes with every part. The mainboard determines, for example, what kind of processor you can use and which RAM devices can be used. So don’t just buy the biggest, fastest, most expensive, but find out what your individual components require from the rest of the hardware.

If you match the individual parts to each other, you will also increase the longevity and stability of your PC.

Incorrect connections

Before the first start-up, check that every screw is tight and that no cables or individual parts are loose. Otherwise, the parts may break off or fall out of their holders during operation. Only if all components are fixed correctly, your computer will work without problems.

Who can I contact if I have any questions?

pc do-it-yourself questions

When assembling your computer – especially the first attempts – it is not unlikely that you will have questions. So that you can configure and assemble your PC exactly as you want it, you have a number of different places to go:

The consumer electronics store

At your local electronics store, you’ll find salespeople who can answer most of your questions ahead of time. Of course, they mainly want to sell something, but they are also experienced in advising their customers on difficult questions.

PC Experts

Going to a PC professional will definitely help you. However, you should also keep in mind that in many cases a consultation is not free. Expert help can be expensive , so you should really only choose this option if you can’t get anywhere else.

Internet communities

On the Internet you can find various forums and websites like ComputerBase, which deal with the assembly of own PCs. If you post your questions there and also mention that you are a layman, other users with more experience will contact you to help you. Often, you’ll even be given different approaches to solving problems, so you’ll have multiple options for solving problems.

I can especially recommend Youtube. With the help of the videos the self-assembly is easier and if you have questions you will be helped immediately in the comments.


There are helpful little manuals for almost every new component, and they always have a section with questions and answers. Here you can definitely take a look and with a little luck find your solution or a tip.


Assembling a computer yourself is not as hard as it seems. Think in advance what your PC should be able to do and what you need for it. Take your time and don’t hesitate to ask questions.

You’ll quickly notice that everything meshes relatively logically. And before you know it, your own computer is standing in front of you, ready and waiting to be used!
