Comparison of Advantages and Disadvantages between 27-inch All-in-One Machine and Same Size Monitor+Host Combination

I. Core advantages

1. Significant space savings.
   All-in-one machine integrates the host into the back of the monitor, without additional main chassis, and the occupied space of the desktop is reduced by about 70%, which is suitable for small-sized houses or scenes with high cleanliness requirements.
2. The cable is simple and beautiful
   Only one power cord is needed (some support wireless mouse and keyboard/network), bid farewell to the multi-line clutter of traditional host+monitor, and the desktop vision is more refreshing.
3. Instant convenience
   All-in-one machine does not need to start the host computer after it is turned on, and supports fast wake-up (such as Windows Hello face recognition), which is suitable for high-frequency use scenarios.
4. Low power consumption and mute
   There is no independent host fan, the noise is less than ＜30dB, and the power consumption is 30% lower than that of the traditional desktop, which is more environmentally friendly.

Second, the main shortcomings

1. Limited performance expansion
   The motherboard is highly integrated, so it can't upgrade the core hardware such as graphics card and CPU, and only supports limited expansion such as memory/hard disk, so it may face performance bottleneck after long-term use.
2. Heat dissipation and stability
   The internal space is compact, and there may be insufficient heat dissipation during high-load operation (such as large-scale games and video rendering), resulting in frequency reduction or jamming.
3. High maintenance and upgrade costs
   The structure of all-in-one machine is closed, so it is difficult for non-professionals to disassemble and maintain it by themselves. Disassembly of some models may affect the warranty.

Third, suggestions for applicable scenarios

Choose an all-in-one machine: users who work at home, take online classes, have light audio and video, and pursue minimalist desktop, especially suitable for renting a house or a small space environment.

Choose monitor+host combination: users with professional design, large-scale games, multi-tasking or need to upgrade their hardware for a long time will give priority to split architecture.
