Chassis? Generally includes the shell, bracket, panel of various switches, indicators, etc.. Shell made of steel and plastic combination, high hardness, mainly play a role in protecting the internal components of the chassis. Bracket is mainly used to fix the motherboard, power supply and various drives.
There are many types of chassis. The more common ones on the market today are AT, ATX, Micro ATX, and the newest BTX-AT chassis, whose full name should be BaBy AT, were mainly used in earlier machines that could only support the installation of AT motherboards.ATX chassis are by far the most common chassis, and support the majority of the types of motherboards that are available today.Micro ATX chassis are built on top of AT chassis, in order to further save space on the desktop, and are therefore smaller than ATX chassis. Each type of chassis can only install the type of motherboard it supports, generally can not be mixed, and the power supply is also different. So you have to be careful when you're shopping.
The latest BTX, short for Balanced Technology Extended. It is a new specification BTX architecture for desktop computing platforms defined and guided by Intel to support new form factors for next-generation computer system design, enabling the industry to achieve an optimal balance of thermal management, system size and shape, and noise.
Features of the new BTX architecture include: support for Low-profile, or narrow-board, design, which will result in a more compact system structure; an optimized design of the motherboard's wiring layout for heat dissipation and airflow movement; and an easier installation of the motherboard and an optimized design of its mechanical properties. Basically, the BTX architecture is divided into three types, which are Standard BTX, Micro BTX and Pico BTX.
From the size point of view of the whole series of BTX platform motherboards are not smaller than the ATX motherboards, so the development of the BTX is not for smaller desktop computers, but a more flexible circuit wiring and modular component areas, is the focus of the BTX.
BTX The most obvious difference between the chassis and the ATX chassis is that the side panel, which used to open only on the left side, has been changed to the right side. The other I/O ports have been moved to the opposite side of the chassis.
