A new computer order shows up and the cart suddenly has a dozen fields you only half understand. The CPU looks expensive, the RAM has three different numbers, nobody pays attention to the power supply, and that is exactly the part where people most often cut corners badly. We know this from practice, we build and repair these every day, and most mistakes happen before the purchase, at the choosing stage.

This article is a hub. It does not cover everything from A to Z, we have separate texts for each topic. Look at what you are dealing with and jump straight to it. We split the sections the way we actually build a machine: the core first, then storage, peripherals, mobile devices, and finally power and connectivity.

The core of the build

This is where everything else is decided. First settle on the CPU, because the socket on the motherboard and the memory type follow from it. The rest is then filled in around these two parts, not the other way round.

Drives and storage

With drives, the most common mix-up is the difference between the connector and the protocol, so start with the article on M.2, SATA vs NVMe and only then work out how much capacity you really need. These two things settle the vast majority of decisions.

Monitor and peripherals

A monitor is something you spend years looking at, so cutting corners there does not pay off. Start with the type of monitor and a comparison of display types, because the panel decides how the image feels after hours of work. A keyboard and mouse are about what suits your hand.

Laptops, phones and tablets

Here it usually comes down to what you do with the device and where, not a spec sheet. For portable computers, how to choose a laptop helps, and with phones people most often circle around the iPhone vs Android question. The rest is about details that only make sense once you know the use.

Power and connectivity

The last section is about what ties it all together. You can save yourself a lot of frustration here if you sort out USB versions and connectors, and with a laptop it is worth reading how to choose a laptop charger, because the wrong adapter is a common reason a machine will not charge at full power.

When to leave it to us

You can handle a lot of this yourself. Picking a drive or a charger from a guide is not rocket science, and we are glad when people get it done on their own. It gets harder when everything has to come together, matching the CPU with the power supply and the board, thinking through cooling, and not overpaying for a part that gets swapped out in a year anyway. That is when it makes more sense to talk it over before the package that does not fit shows up.

If you want a new build or an upgrade at home, take a look at PC building and upgrades. For companies we build custom hardware based on what you actually need to run. And if you are unsure, get in touch and we will go through it with you before you order anything.
