Computer concept:

Your personal computer only needs to be built for the purpose you need:

· Professionally (e.g. for billing, e-mail, banking, information) in your home office

· Private (e.g. for communication through e-mail, chat, videochat, posts or for gaming)

· Both for entertainment for / with others (on Twitch, youtube, itunes, etc.)

For every application you want, there are certain different technical system requirements for it to work, which you can research with the manufacturer of the application in order to design a computer system. The final composition still depends on the standards of the manufactury (e.g. ATX form factor) and your personal taste (design). For cost reasons, you should only spend so much money for the application to work ...

There are supplied manuals and (video) instructions on the Internet (youtube) for assembly, but you should always consult an experienced specialist who will configure the system (the BIOS and, for example, Windows).

Casing:

We prioritize a case with ATX form factor (standard) for the boards because of the structure.

The case should be big enough that all components fit in and have a little "air", but also not unnecessarily waste space due to oversize. Usually a midi tower is sufficient.

It should have an easily accessible large on / off button, reboot button, function indicator lights, front connections for audio (headset and microphone), 4 USB ports and spaces for a front fan (to suck in air) and a back fan (to blow air out) as well as one Power supply that provides enough power (especially for a powerful graphics card for 3D gaming) ~ 500 - 650 watts, but then you have to do a total calculation again in special cases ...

Cases with plug-in closures (instead of screws) for the components are practical ...

The design is a matter of taste in terms of color, logos and see-through side windows.

Fan:

We prioritize 4-pin fans with damping and ball bearings in the size of the spaces on the case. With the fourth pin it is possible to have the fans automatically calibrated in the BIOS (set PWM mode) in order to have the optimal setting: Sufficient cooling air, but not too much noise than necessary. Using the blades on the fan, you can see the direction of the air flow ...

Mainboard:

Since we have chosen an ATX for the case, we can now take a mainboard with ATX that fits the structure (size, structure, screw holes). To use certain processors and main memory chips, you also need corresponding mainboards, as well as if you want certain slots or the latest technology that performs better, whereby it is recommended to only consider the application, otherwise the system will be unnecessarily expensive. You can look at performance comparisons on the Internet.

According to renowned specialist magazines, the (secure) function (over a longer period of time) that the qualitative components (e.g. capacitors) and sophisticated (engineering) technology fulfill is important ...

Processor:

Most of the time, the system requirements for the application include a processor that you need and a corresponding mainboard. In the case of Intel processors, one can use ark.intel

read about what fits together, including the main memory chips. More precise differences between Intel and AMD processors are in technical gimmicks and the price. We advise against using powerful Intel K processors because of the high heat development (+ 33 °). A copper fan is recommended to cool the processor because of its high thermal conductivity.

Memory chips:

Here you take 2-4 chips for the 4 memory banks on the mainboard, which match the technical characteristics of the mainboard and also the processor. On the one hand, the mainboard must support the chips (read the manufacturer's specification), on the other hand, they must be processor-compatible, especially when it comes to speed. In general, a total of 16 - 32GB is sufficient for Windows 10. You create an additional virtual memory (pagefile.sys) that Windows manages itself (size is dynamically adjusted) on the SSD via the advanced system settings ...

Graphic card:

There are various graphics cards with varying performance levels. For office work (2D desktop), a passively cooled graphics card that can also play videos well is sufficient. However, it should now support 4K resolution of images and videos (even via a suitable 4K monitor with the best HDMI cable). For gaming, game manufacturers provide technical specifications for each game regarding the required graphics card performance. The aim is basically for the graphics card to bring the individual images of the game to the screen at the appropriate resolution in a certain time (frames per second). This prevents stuttering and ensures smooth gameplay. This makes it look better and also makes the game more enjoyable. Other graphics features are also important (especially anti-aliasing, which smooths the edges of the pixels).

The monitor should also be compatible, i.e. support the necessary resolution and frame rate.

Hard disks:

Meanwhile, instead of the mechanical hard disks (HDD), those with the electronic components "chips" (SSD) are used. These are therefore usually less prone to vibrations and bumps and in some cases are much faster (read, write 500 MB / s). They are connected to the mainboard via the SATA bus and can be attached to the housing using appropriate mounting frames. We recommend an SSD for the operating system (size: 128 - 256 GB) and an SSD (1 TB or larger) for media (music, films, etc.), which is particularly good at sequential reading (for data sets arranged one after the other) ... and possibly a third SSD (big enough) for a game ...

CD-ROM, DVD, BLUE-RAY (burner):

Depending on what you have for the requirements for the format (for software installation media or playback) or you need a size for your own data for backup, you can use CD, DVD or Blu-ray players, burners and blanks. There are also options for rewriting the blanks, labeling them and storing them on very durable blanks ...

Cleaning the LW with certain CDs (with brushes and liquid) every 6 months (with several runs) seems to bring something to one or the other ("works again"), but not to the other ...

USB sticks:

With a high transfer rate, preferably USB 3.1 (must be supported by the PC), correspondingly large.
