A PC case, it's not just a "box" where you store your motherboard and graphics card. It plays a crucial role on:

• The temperature of your components → poor ventilation = decreased performance.
• The silence → good cases are designed to dampen noise.
• Scalability → if you want to add a second graphics card, good airflow or an AIO, it is better to have space.
• The style → tempered glass side panel, RGB LED, simple or futuristic design, up to you.

Before buying, you have to choose the right case format depending on your motherboard (ATX, Micro-ATX, Mini-ITX) and the space you have at home:

A very common mistake in choosing a case is to consider that all ATX cases are equal in terms of size (or other). We really recommend you to look at the dimensions of the cases in addition to the format , you can have bad surprises - I have already had a bad one so I speak from experience! You can find the dimensions directly on the manufacturer's website.

Here is a selection of best gaming PC cases at the moment, according to user feedback and stocks:

1. Lian Li Lancool III RGB - monstrous airflow, clean RGB, ultra easy installation

Customizing your setup also involves the look of your case:

• White PC case : for a minimalist, clean style, often associated with pastel RGB.
• Black case : more classic, discreet, professional.
• RGB Case : perfect for gaming setups that shine.
• Aquarium case : glassed all over, ideal for showcase fans.

The good news is that no matter what you want, there is something for every budget.

Here are the brands recommended by DropReference:

• NZXT - sleek design, good quality of finish
• Corsair - excellent cases for cooling
• Fractal Design for those seeking silence
• Cooler Master - very good value for money
• Lian Li - high-end, design and top performance (personally, they are my favorites with their design!)

💡 Tip: always prioritize optimized airflow (mesh at the front, dust filters) over a 100% glass case without ventilation.

Some quick tips:

• Check motherboard + GPU + AIO compatibility
• Provide enough slots for SSD/HDD
• Choose a case with front USB-C if you have a recent device
• Do not neglect cable management: it changes everything

What size case for my setup?

If you have an ATX motherboard, take a Mid or Full Tower. For compact setups, opt for a Mini-ITX case.

Glass or non-glass case?

The glass panel looks stylish, especially with RGB. But remember ventilation. If the case is all glass without mesh, you may risk overheating.

Does a case influence performance?

Indirectly yes. Poor airflow can cause components to heat up, which reduces overall performance.
