AT: Standard size motherboard, named after the first use of IBM PC/A, some 486 and 586 motherboards also use AT structure layout .
Baby AT: Pocket size motherboard, smaller than AT motherboard, hence the name. The integrated motherboards of many original machines first adopt this motherboard structure .
ATX: The improved AT motherboard has optimized the layout of the components on the motherboard, has better heat dissipation and integration, and needs to be used with a special ATX chassis .
BTX: It is an improved version of the ATX motherboard . It uses a low-profile design to make the component layout more compact. In view of the movement characteristics of the airflow inside and outside the chassis, the motherboard engineers optimized the layout of the motherboard to make the computer's heat dissipation performance and efficiency higher, less noise, and easier to install and remove the motherboard.
BTX formulated three specifications at the beginning, namely BTX, Micro BTX and Pico BTX. The width of the three types of BTX are the same, 266.7mm, the difference lies in the size and scalability of the motherboard.
All-in-one motherboard: It integrates multiple circuits such as sound and display. Generally, it can work without inserting a card. It has the advantages of high integration and space saving, but it also has the disadvantages of inconvenient maintenance and difficult upgrades. Most of the original brand machines are used.
NLX: Intel's latest motherboard structure . The biggest feature is that the motherboard and CPU upgrades are flexible, convenient and effective. It is no longer necessary to update the motherboard design every time a CPU is introduced. In addition, there are some deformation structures of the above motherboards, such as ASUS motherboards. 3/4 Baby AT size motherboard structure. mining motherboard computer monitors
