The expandability of the open chassis hassis has a natural advantage in the external connection of multiple devices. Its design without a closed shell provides more space for interface layout. Various interfaces on the motherboard, such as USB, HDMI, audio interface, etc., can be directly exposed to the outside, without being limited by the panel opening position like traditional chassis. Users do not need to bend down to find interfaces when connecting external devices, and the plug-in and unplug process is more convenient. At the same time, this design allows more expansion interface positions to be reserved around the hassis, providing a physical basis for connecting multiple devices and reducing the inconvenience caused by crowded interfaces.
The structural design of the open hassis facilitates the installation of expansion cards, indirectly improving the external connection capabilities of multiple devices. Expansion cards such as graphics cards, sound cards, and network cards can be directly fixed on the bracket of the hassis, and their interfaces are completely exposed and will not be blocked by the chassis baffle. When connecting external monitors, network cables or other devices, the connection path is more direct. For scenarios that require multi-monitor output, such as design work or multitasking, the open hassis allows multiple video interfaces of the graphics card to be used efficiently at the same time, without worrying about the limitations of the chassis space on the connection cables, and meeting complex external connection requirements.
The modular design of hassis provides flexibility for expansion interfaces. Many open chassis havesis are equipped with replaceable interface expansion modules. Users can add expansion components such as USB hubs and Thunderbolt interfaces as needed. These modules are directly installed on the edge of the hassis and connected to the motherboard through cables. They do not occupy internal space and can provide interfaces for external devices nearby. This modular expansion method allows users to flexibly adjust the interface configuration according to the number and type of devices, and easily cope with the scenario of multiple devices connected at the same time.
The open layout is conducive to the cable management of external devices, and indirectly improves the stability of multi-device operation. When multiple devices are connected externally, the cables are easy to entangle and knot, affecting the normal operation of the devices. The cables of the open hassis can be arranged in an orderly manner along the edge of the hassis or the reserved cable management rack to avoid the cables squeezing each other or blocking the hardware, ensuring that the connection cables of each device can remain unobstructed, and reducing the failure of external devices caused by cable problems. This neat wiring environment makes it more reliable when multiple devices are running simultaneously.
The space margin of the hassis provides the possibility of installing large external devices. Some external devices such as external hard disk arrays and high-performance graphics card docks are large in size, and the space around traditional chassis is narrow, making it difficult to properly place them. Open chassis hassis are usually equipped with spacious countertops or brackets, which can directly fix large external devices next to them and connect them to the host through short cables, which not only shortens the data transmission distance, but also avoids the heat dissipation problem caused by device stacking, making it more feasible to connect multiple devices in space.
The open design has a positive effect on the heat dissipation coordination when multiple devices are connected. Multiple devices running at the same time will generate more heat. Traditional chassis may cause poor heat dissipation due to the closed structure, affecting the performance of the host and external devices. The open hassis itself has good heat dissipation and can quickly dissipate the internal heat of the host. At the same time, it reserves sufficient heat dissipation space for external devices to avoid connection interruption or performance degradation due to overheating of the device, ensuring the long-term stable operation of multiple devices, and indirectly improving the practicality of scalability.
The compatibility design of hassis allows external devices of different specifications to be connected smoothly. Whether it is an old PS/2 interface device or a new Type-C device, the interface layout of the open hassis does not need to consider the chassis compatibility restrictions, and the motherboard native interface or expansion interface can directly match the device. For special devices that require adapters, the open space also makes it easy to place the adapters, which will not be unable to be installed due to the small space inside the chassis. This wide compatibility makes the external connection of multiple devices almost unrestricted and can meet diverse external connection needs.
