What are the most common types of computer cases

The most commonly used computer case type is ATX, which supports most types of motherboards today. The chassis sold on the market are mainly ATX and Micro ATX chassis; ATX chassis is much better than Micro ATX chassis in terms of heat dissipation and performance expansion, and ATX is still the mainstream of the market.

The chassis generally includes a shell, a bracket, various switches and indicators on the panel, etc. The outer casing is made of a combination of steel plate and plastic, has high hardness, and mainly protects the internal components of the chassis. The bracket is mainly used to fix the motherboard, power supply and various drives.

As a part of computer accessories, the main role of the chassis is to place and fix various computer accessories, and to play a supporting and protective role. In addition, the computer case plays an important role in shielding electromagnetic radiation. Although it is not a very important configuration in DIY, using a poor-quality chassis can easily short-circuit the motherboard and chassis, making the computer system very unstable.

There are many types of chassis. The most common ones in the market now are AT, ATX, Micro ATX and the latest BTX-AT chassis. The full name should be BaBy AT, which is mainly used in early machines that can only support the installation of AT motherboards. ATX chassis is currently the most common chassis and supports most types of motherboards. Micro ATX chassis is built on the basis of AT chassis. In order to further save desktop space, it is smaller than ATX chassis. Each type of chassis can only be installed with the type of motherboard it supports. Generally, they cannot be mixed, and the power supplies are also different. So everyone must pay attention when purchasing.

The most commonly used computer case type is ATX, which supports most types of motherboards today.

The full name of ATX in English is AT Extended. Due to the irregularity of the Baby AT motherboard market and the outdated AT motherboard structure, Intel Corporation released a specification for PCs in 1995 in order to standardize the motherboard structure. Structure - extended AT structure, which is the ATX motherboard standard, and the chassis derived from the ATX specification is also called an ATX chassis.

Compared with the Baby/Mini-AT structure, the layout of ATX has made considerable changes: Baby-AT uses a horizontal structure chassis, and the I/O interface is located on the narrow side of the motherboard (24.4cm), while ATX changed the chassis to a vertical structure, and moved the I/O interfaces to the wide side (30.5cm) and made it into a "backplane" form.

In addition, ATX also stipulates that the hot air from the CPU radiator must be exhausted, which not only enhances heat dissipation, but also reduces dust accumulation in the chassis. On the basis of the ATX specification, several specifications such as ATX, Micro ATX, NLX, WTX, MiniATX, and Flex-ATX are derived.

The chassis currently on the market are mainly ATX and Micro ATX chassis. Micro ATX chassis is smaller in size and has limited scalability, and is only suitable for users who do not have high requirements for computer performance; while ATX chassis is much better than Micro ATX chassis in terms of heat dissipation and performance expansion, and ATX is still the mainstream in the market. .
