Background technique

A computer can achieve a variety of functions, such as computing functions, storage functions, word processing functions, etc., through the multiple components housed in the computer. In recent years, in order to improve the external design of the computer, so that the computer can be installed in a small and compact space, compared with the traditional computer, the ultra-thin computer with reduced volume and thickness is a research hotspot.

However, ultra-thin computers also have some drawbacks. For example, the headroom for high heat dissipation is reduced, and the internal space in which computer components can be embedded is reduced. These problems are also becoming more and more prominent due to the increase in processing speed and storage capacity of computers.

In addition, traditional ultra-thin computers use mini-ITX-type motherboards similar to notebook motherboards to avoid installing expansion cards. Also, even if an expansion card is allowed to be installed, only a small expansion card can be used, so the choice of expansion cards becomes very narrow. Therefore, the scalability of traditional ultra-thin computers is very limited.

However, when it is necessary to replace motherboards and expansion cards with larger and larger sizes, in order to improve computer performance and meet the needs of consumers, the location of the PCI slots of the motherboard varies according to the type of motherboard and manufacturer, so the fixed expansion card The location of the slot and the location of the connecting portion of the rear panel of the housing usually do not match.

Also, when installing an advanced expansion card in an ultra-slim computer, when the expansion card is only fixed to the rear panel of the case, it may be biased by its own weight, or it may be damaged by external shocks.

In addition, when using a riser card, the cooler of the expansion card is installed on the lower part of the motherboard facing downward, so that the hot air heated by the motherboard is drawn into the cooler of the expansion card, correspondingly, the cooler of the graphics card is also larger, and Not suitable for ultra-thin computers.
