Best Material for Gaming PC Casing

There are many factors to consider when choosing a gaming PC case, for example, dimensions. Depending on this, you can determine how much space it will take on the table. But, according to experts, it is equally important to determine the best material from which the case is made when buying.

The mass of the gaming PC case, the rigidity of fastening of all elements located inside, the ability to withstand external mechanical influences, beautiful design are directly dependent on the material from which the case is made. As a rule, gaming pc cases are made of two metals. These are aluminum and steel.

Let’s discuss which material is best for your gaming PC casing. In this article, we will compare aluminum and steel chassis.

Aluminum is used in chassis, let’s say, premium class. The main reasons for using this material lie in its properties. Aluminum is a lightweight, sustainable and durable material widely used for interior decoration. And with a high probability, the case you bought from this metal will fit perfectly into your interior. Cases of high-quality mobile devices are also made of aluminum. Looks nice, even plastic finished in aluminum. The only drawback or advantage is its price.

For the environmental advantages, aluminum is easy to recycle. Recycling significantly reduces the need for resources and minimizes environmental pollution. Aluminum can be recycled and reused almost unlimited times. For example, in the automobile and high-tech industries, aluminum can easily replace plastic, one of the primary sources of waste on the planet.

It must be admitted that, in many cases, an aluminum case should be considered the best option, especially for those PCs whose system is very heated up.

For intensely heated systems, aluminum computer cases are better suited. After all, they dissipate heat with their entire surface. Gaming PC cases made of steel have better sound insulation.

Steel casings are inexpensive. Steel is a variable metal, although it usually is substantially less expensive than aluminum. Steel cases are generally 25-50 percent less costly per case size. They don’t have that high-end feel, but if that’s not important to you, steel casing will far better suit you with this material.

In the weight section, indeed, the cases made with steel are usually considerably heavier than those made of aluminum (depending, to a large extent, on the thickness of the sheet metal used by the manufacturer, obviously).This greater weight also translates into the higher stability of these boxes. As for the wall thickness, Steel cases with a thickness of 0.5-0.8 mm is a sign of good quality. It will reliably protect your components, and no vibrations and rattling will spread. Thinner-walled chassis are more prone to vibration and unwanted noise such as rattling.

But, an aspect that we have not mentioned before is that aluminum can be scratched and dented much more quickly than steel. So, if you are prone to hitting your gaming pc case, we advise you to buy steel-made cases.


Aluminum casings are the ones we choose since they are more in line with the modern PC user’s needs and the demands of professional clients.An aluminum case is the best choice as it conducts heat well.

VOLTA‘s PC chassis is predominantly built of aluminum for thermal conductivity for natural convection cooling. Aluminum is lighter than steel, which is good for your back as you need to move your computer from time to time. The brushed aluminum looks great.

Do not go after the cheapest steel cases – they are usually made of low-quality stamping and have various backlashes. And the reliability of the elements leaves much to be desired. The next time you buy a new gaming PC, you won’t have to search forums to see better – steel or aluminum. Both have their advantages, but if you choose durable, quality aluminum, you can enjoy a lightweight, elegant, and exceptionally durable PC when you’re on the go.
