A PC case is not just a shell that holds components. It is a full-fledged and essential part of a high-performance computer. The quality and stability of your hardware, as well as upgrade potential, directly depend on it. Let’s explore the key features of a modern PC case and highlight the best options of 2025.
Form Factor and Compatibility
The size of a desktop PC case must support the installation of all modern components. Otherwise, you may encounter issues with assembly or future upgrades.
A high-quality case should support:
The largest graphics cards up to 330 mm in length;
Power supplies of ATX and SFX form factors;
Three-section liquid cooling systems;
Multiple 120 mm or 140 mm fans;
The largest tower coolers up to 180 mm in height;
Motherboards of ATX, Micro-ATX, and Mini-ATX standards.
If a case meets these requirements, you won’t face any difficulties when building or upgrading your PC. However, this doesn't mean that cases with different specifications should be dismissed. For example, if you plan to use a liquid cooling system instead of an air cooler, the maximum supported tower cooler height becomes irrelevant. The same applies to other parameters – if you're certain you don't need support for specific form factors, you can safely ignore those features.
Ventilation Openings and Dust Filters
High-performance components in gaming PCs and workstations generate a lot of heat. To keep temperatures under control, a PC case must include:
Ventilation openings;
Dust filters;
Fans.
Ventilation openings allow cool air to enter the case, reducing the temperature of the components.
Since air contains a lot of dust, these openings should be equipped with dust filters. Filters help trap dust, keeping the interior of your PC cleaner. However, this doesn’t mean you won’t need to clean your system at all. Dust filters only catch larger particles, while finer dust can still accumulate inside the case. That’s why occasional cleaning is still necessary – just much less frequently with filters in place.
Many cases come with pre-installed fans. These help expel hot air and bring in cool air, further improving cooling efficiency.
If a case doesn’t include pre-installed fans, you can always purchase them separately. In fact, manufacturers often cut costs by including lower-quality fans in their cases. By buying fans separately, you can choose high-performance models for better airflow and cooling.
Drive Bays for HDD and SSD Storage
A PC case should have enough drive bays to accommodate all the storage devices you need. Otherwise, you won’t be able to install additional drives inside your computer. Ideally, a case should include:
Multiple 2.5-inch drive bays;
Multiple 3.5-inch drive bays.
Most modern PCs are built without traditional 2.5-inch and 3.5-inch drives, relying instead on NVMe SSDs that connect directly to the motherboard. However, even in this case, it’s wise to choose a case with extra drive bays. In the future, you may want to expand your storage, and your motherboard might not have enough free NVMe slots.
Nearly all modern PC cases feature a side viewing window, which is typically made from one of two materials:
Acrylic;
Tempered glass.
Acrylic is a budget-friendly material but scratches very easily. Even wiping it with a soft cloth to remove smudges can leave visible scratches. This makes acrylic the worst option for a viewing window.
Tempered glass, on the other hand, is highly durable and resistant to scratches. It maintains its original appearance over time and provides a more premium look. This makes tempered glass the best choice for a modern PC case.
