How to Build or Upgrade a PC in Germany Without the Guesswork
You have moved to Germany, your old desktop stayed behind or arrived with a UK plug and a tired graphics card, and you want a machine that handles a new game, a 4K edit or a long day of remote work. Building or upgrading a PC here is very doable, even if your German stops at “Warenkorb”. The parts are the same worldwide; what changes is knowing which ones matter and where to buy them with a proper returns route.
This guide covers who should build or upgrade, what each component does and what to look for. It then shows where ALTERNATE, the long-running electronics retailer based in Linden, Hesse, fits in, including a configurator that checks compatibility for you.

Who should build or upgrade rather than buy off the shelf
Gamers and creators. If one component limits you, usually the graphics card or memory, an upgrade fixes the bottleneck without replacing everything else.
People with specific needs. Quiet home offices, small cases for a flat with little space and machines for a particular piece of software all benefit from choosing each part yourself.
Anyone who wants to keep the machine for years. A self-chosen system is easier to upgrade later because you know exactly what is inside it.
The parts, and which ones deserve the budget
Processor (CPU). The CPU sets the platform. Your choice of CPU decides which motherboard socket you need, so pick it first. For gaming, a mid-range chip paired with a strong graphics card usually beats a top chip with a weak one.
Graphics card (GPU). For gaming and much creative work, this is where the money makes the most visible difference. Check its length against the case and its power needs against the power supply.
Motherboard. It must match the CPU socket and the memory generation. Beyond that, look at the number of M.2 slots for SSDs, USB ports on the back panel and whether Wi-Fi is built in.
Memory (RAM). Buy the generation your motherboard supports, ideally as a matched kit of two modules, so the system can run them in dual channel.
Storage (SSD). An NVMe SSD in an M.2 slot makes the whole system feel quick. Many builders use one fast drive for the system and games, then add capacity later.
Power supply (PSU). This is the part people underspend on. Choose a reputable unit with headroom above your components’ combined draw and an efficiency rating, as it feeds everything else.
Case, cooler and fans. Airflow keeps components quieter and longer-lived. Check that the CPU cooler fits under the side panel and that the case takes your graphics card.
What to look for before you click “buy”
Compatibility. Socket, memory generation, cooler height, GPU length and power connectors are where most first builds go wrong. A configurator that checks these for you removes most of the risk.
Balance. Spend in proportion. A system is only as quick as its slowest relevant part for the job you do most.
Returns and support you can use. As an English speaker in Germany, a retailer with a clear return right and a physical service point is worth a lot when something arrives faulty.
Assembly. If you have never seated a CPU or routed cables, paying for professional assembly is a sensible choice.
Where ALTERNATE fits: parts, configurator and in-house assembly
ALTERNATE describes itself as one of the first German online shops for IT products, launched in 1997. It says it now stocks more than 85,000 products, from graphics cards to garden tools. The PC side sits under its Hardware, PC and Gaming categories.
The PC-Konfigurator. This is the centre of ALTERNATE’s offer for builders. It walks you through the processor, motherboard, cooler, memory, graphics card, SSD, case, fans, power supply and operating system, with optional peripherals afterwards. According to ALTERNATE, the configurator continuously checks your selection in the background so that only compatible parts appear together. The tool also shows estimated gaming performance based on 3DMark benchmarks. ALTERNATE notes that these figures are indicative rather than guaranteed.
Assembly and testing in Linden. You can order the parts loose and build the PC yourself, or have ALTERNATE put it together. The company says every system is assembled in its own PC production at its Linden headquarters and checked for functionality afterwards. It offers a 48-hour load test as an option, available only when it does the assembly. ALTERNATE also points out that assembled orders take longer to deliver.
Ready-made Wunsch-PCs. If you would rather start from a tested base, ALTERNATE’s Wunsch-PC range offers preset configurations you can adjust. The shop advertises free shipping and a 30-day return right on these.

Upgrading a machine you already own or are about to buy
Not every project needs a full build. ALTERNATE runs a Notebook and PC Upgrade Service. You choose a laptop or PC in the shop and request more memory or a larger SSD, and ALTERNATE checks feasibility and contacts you before fitting it. Items marked as shipping-only cannot be reconfigured.
If you live within reach of central Hesse, the Linden site adds in-person options. ALTERNATE lists a store, a service counter for complaints, PC repair and upgrades, and pickup warehouses in Linden and nearby Pohlheim, so you can collect an order rather than wait for delivery. Check the current opening hours on the site before you travel.
Paying. ALTERNATE lists PayPal instalments, SEPA direct debit and, for business customers, leasing and invoice purchase after a credit check. Freelancers equipping a home office can also ask its B2B team for a project quote.
The upgrade worth making this year
For most people, the upgrade that changes daily use most is the graphics card for gaming, or an NVMe SSD with more memory for work. If you are starting from scratch, the configurator takes the guesswork out of compatibility. Assembly and the optional 48-hour test in Linden mean the machine arrives ready to switch on.
Choose the part that holds you back, check it against the rest of your system and order from a shop that will build, test and take it back if needed. That is a comfortable way to get a better PC in a country where you are still learning the vocabulary.
