機箱的存在與否其實根本不影響電腦的正常運行但是其實一個正常的機箱是有他的意義的，而且在某些方面確實會對主機造成影響

The existence or absence of a computer case does not actually affect the normal operation of the computer, but in fact, a normal computer case has its own significance and can indeed have an impact on the host in some aspects

第一點就是暴露在外部環境中硬件更容易落灰，機箱很多時候都充當了擋灰的功能，如果不要機箱，你建議更過分地保持室內整潔和更經常地清理硬件灰塵；

The first point is that hardware is more prone to dust when exposed to the external environment. Chassis often serves as a dust barrier. If you don't want a chassis, you must maintain indoor cleanliness and clean hardware dust more frequently;

第二點機箱是對硬件的一個保護，阻擋水、掉落物體、人為誤觸的影響，長期暴露在外部環境的硬件很容易受到傷害，舉個例子，有水撒在主板上就直接沒了，要是有個機箱那至少不會因此而損壞硬件。

The second point is that the chassis is a protection for hardware, blocking the effects of water, falling objects, and human touch. Hardware exposed to the external environment for a long time is easily damaged. For example, if water is spilled on the motherboard, it will disappear directly. If there is a chassis, at least it will not damage the hardware.

第三點顏值和散熱問題，一個不好的機箱會對散熱帶來壞影響，而一個好的機箱和合理的風道設計會更容易排出cpu周圍的熱氣，并可能會對主板供電mos管帶來一定的散熱加持，這個是直接裸露在外的硬件無法達到的效果，畢竟除開散熱風扇的風道上，其他部位的散熱全靠擴散了所以可以看出一個機箱其實更多的是帶來對硬件的保護，機箱主要的影響還是影響了整體系統的安全性。再工廠一眼看過去全是線好還是有個柜子板板正正的好？

The third point is about appearance and heat dissipation. A poor chassis can have a negative impact on heat dissipation, while a good chassis and a reasonable air duct design can easily exhaust the hot air around the CPU and may provide some heat dissipation support for the motherboard power supply MOSFETs. This is an effect that hardware exposed directly cannot achieve, after all, except for the air duct of the cooling fan, the heat dissipation of other parts relies on diffusion. Therefore, it can be seen that a chassis actually brings more protection to the hardware, and the main impact of the chassis is still on the overall system security. Is it better to have a straight cabinet board or to have all the lines in the factory at a glance?

不要機箱可以不可以，當然可以，但是意味著你建議更加細心的呵護就是了。

It's okay not to have a computer case, of course, but it means you have to take more careful care of it.
