A PC case, also known as a tower or chassis, holds most of the hardware components in your computer. This includes the motherboard, power supply (PSU), CPU and GPU as well as RAM and hard drives for storage. The case itself acts as a heat sink, keeping the internal components cool and preventing overheating that can lead to faulty hardware or even system failure.
There are different cases in various shapes and sizes, each with their own advantages depending on your needs. The three most common PC cases are full-tower, mid-tower and mini-tower, with the latter being the smallest in terms of size. Generally, mid tower cases work with most mainstream motherboards and are ideal for home or office use. They usually have between two and four external bays (to hold SSDs, 3.5-inch hard drives or 5.25-inch optical drives) and are fairly spacious with a good amount of air circulation.
Larger form factors like EATX full and ATX super towers are typically reserved for custom builds or ultra-high-end gaming rigs that require extra space to support multiple GPUs, AIO liquid cooling and more. These are quite tall and have a large opening at the back that allows the PSU’s built-in fan to draw cool air through the case. Many of these cases feature front USB and audio ports, allowing you to connect devices without having to fish around the rear. In the higher price range, you can expect to find more features including water-cooling compatibility, tool-less design and aesthetic options such as tempered glass side panels. PC case
