Essential Measurements for Building Gaming Desktop PCs

Understand Motherboard Compatibility

Firstly, you should ensure that the motherboard fits into the PC case. Motherboards are available in different sizes such as ATX, Micro-ATX, and Mini-ITX. PC cases are dimensioned accordingly.

A full-tower case can accommodate an ATX mainboard, while a Mini-ITX case is only suitable for Mini-ITX motherboards. Check the specifications of your case to ensure that the motherboard is compatible.

Evaluate Graphics Card Dimensions

The length, width, and height of the graphics card are also important factors. Modern graphics cards are often equipped with massive cooling solutions that take up a lot of space.

• In small cases or when mounting a CPU radiator in the front, the length can be a problem.
• Check the specifications of both the case and the graphics card carefully.

Ensure CPU Cooler Fits

The height of the CPU cooler and RAM module is also a crucial aspect. Modern air coolers are often large and can be too high for certain cases.

Make sure that the cooler fits into the housing and that the side panel can close. Also, consider RAM height, especially if equipped with elaborate heatsinks.

Account for Drive Bays

Drive bays are another point to consider. There are two main sizes for internal storage media: 2.5 inch for SSDs and slim HDDs, and 3.5 inch for traditional hard drives.

Modern cases often no longer have front drive bays, but it's crucial to ensure enough space for your desired drives.

Check Case Fan Sizes

The size of case fans is also important. Most fans are universal but vary in size.

Ensure the fans fit in the spaces provided. If your graphics card length restricts front fan space, you can install fans later.

Power Supply Considerations

Pay attention to the form factor and cable lengths of the power supply unit. The most common form factors are ATX PS/2 and SFX for smaller cases.

Check that your power supply has sufficient connections and that cable lengths are correct for effective management within the case.

Consider Liquid Cooling Options

If you prefer liquid cooling (all-in-one), consider the radiator size. Ensure your case specifies the maximum supported size.

Also, make sure your GPU isn't excessively long if installing the heat exchanger in front.

With these measurements, you are well equipped to build a computer without compatibility and space issues.
