A computer case is a “box” which houses all of the internal components of your desktop PC. Computer cases come in various shapes and sizes. Some of them are plain simple, while others have staggering visual design, and come with a wide variety of different features, such as RGB lighting, full liquid cooling support, and even built-in fan controllers and CPU temperature displays.

When choosing a PC case for your next gaming or office build, make sure that there is enough physical space inside it for the selected computer components. A full-size PC case can accommodate huge E-ATX motherboard, while most mid-tower cases offer enough room to install standard ATX or microATX boards. If you plan to build a small gaming computer, then you’ll need to get a case that supports mini-ITX motherboards. Most of these cases don’t offer enough GPU clearance to accommodate long graphics card, so you’ll also have to find a suitably long GPU.

Massive big tower cases are often bulky and too heavy to move, but offer great support for building custom liquid cooling loops. These days most PC cases feature tempered-glass side panels, thus enabling you to easily see what’s inside your computer, and also feature improved layouts for efficient cable management. High-quality cases offer better construction materials, and also offer better solutions to various building problems, such as ventilation, and convenient placement of hard drives.

Once you decide which PC case better suits your need, the fun part happens next. From installing custom coolers, to adding RGB lighting, and PC fans, the computer assembly process is able to offer limitless possibilities. Here are our top picks for the best PC cases in 2021. Take a look, and decide which one you like more.
