The biggest advantage of small chassis is small, space saving, simple and beautiful appearance, less dust if well protected. The disadvantage is that it is not conducive to heat dissipation. When upgrading, because the motherboard you bought has to adapt to the small chassis, it is basically a small board, so it is difficult to upgrade and there are few slots.
常规的机箱一般是立体式，或桌面式，再就是横式。电脑机箱尺寸，目前市面上根据不同的规格有不同的方案。电脑机箱的规格一般会分为 ATX，MicroATX 和 ITX 三种，在用户购买哪种规格的机箱，其主要是根据主板的尺寸决定。机箱作为台式机电脑一个重要组成部分，它的性能会直接影响电脑的工作。
Conventional chassis is generally three-dimensional, or desktop, and then horizontal. The size of computer case is different according to different specifications. The specifications of computer chassis are generally divided into ATX, microATX and itx. The specification of the chassis purchased by users is mainly determined by the size of the motherboard. Chassis as an important part of desktop computer, its performance will directly affect the work of the computer.
目前，机箱尺寸是没有绝对标准的，各个机箱厂商做出的尺寸都不尽相同，只有一个大致范围的。ATX 机箱，可兼容 ATX 和 Micro ATX 两种主板，即大尺寸机箱，范围尺寸是：450(D)×185(W)×420(H)mm。Micro ATX 机箱能兼容 Micro ATX 主板，即普通机箱，范围尺寸是：405(D)×175(W)×390(H)mm。ITX 机箱只能容纳 ITX 主板，即迷你机箱，范围尺寸是：355(D)×88(W)×290(H)mm。
At present, there is no absolute standard for the size of the chassis. The sizes made by various chassis manufacturers are not the same. There is only one approximate range. ATX chassis, compatible with ATX and micro ATX motherboards, namely large size chassis, the range size is 450 (d) × 185(W) × 420(H)mm。 Micro ATX chassis can be compatible with micro ATX motherboard, that is, ordinary chassis, the range size is 405 (d) × 175(W) × 390(H)mm。 Itx chassis can only accommodate itx motherboard, i.e. Mini chassis. The range size is 355 (d) × 88(W) × 290(H)mm。
Influence of chassis size on host
1. If the chassis has a spacious internal space, the air flow and hardware cooling will be more ideal.
2. Today’s game players pursue high-end machines. The performance of the graphics card is more and more powerful, and the body of the graphics card is correspondingly longer and larger. The large chassis can leave enough space for the graphics card, which is convenient for installation and heat dissipation.
3. In addition, with the high performance of CPU and memory of the computer, the heat inside the chassis is also relatively increased. For the convenience of heat dissipation, the number of cooling fans in the chassis has also become a trend. The large chassis can reserve sufficient installation positions for these cooling fans.
4. The mainframe backplane wiring and neat wiring can bring benefits to the heat dissipation and aesthetics of the whole chassis, and the larger chassis also has certain advantages in this aspect.
Advantages of mini host
Small and portable
小巧是迷你主机最大的特点，其体积一般是传统台式主机体积的 1/30，相当于一本 300 页的书本厚度，长宽如 A5 纸张般大小。
Small is the biggest feature of mini host, its volume is generally 1 / 30 of the volume of traditional desktop host, equivalent to the thickness of a 300 page book, length and width as A5 paper size.
Save space and resources
Mini host small size, can stand can lie can be fixed rack, can be placed in any small corner of the table, can also be fixed with a dedicated rack in the back of the monitor or video screen, for now office or home life to make a broader space resources, but also a clean desktop space. In modern life, limited resources, rising house prices, rent, office equipment, household appliances, etc. are also increasingly in need of mini compact shape, mini mainframe is also catering to people’s needs.
Fashionable and beautiful
Most of the traditional large desktop computer’s old-fashioned shape can no longer meet the aesthetic needs of modern people, and the mini computer’s fashionable appearance design, combined with small and exquisite, whether placed on the desk, living room or study, are very artistic, bringing a more pleasant experience to life and work.
Low power consumption, energy saving and power saving
迷你主机采用低功耗处理器，热设计功耗 TDP 一般在 10W-17W 上下，而传统大台式主机功耗平均在 100W~150W，是迷你主机功耗的 10 倍甚至更大。
Mini host uses low-power processor, thermal design power consumption TDP is generally about 10w-17w, while traditional desktop host power consumption is 100w-150w, which is 10 times or more than Mini host power consumption.
Silent environmental protection
传统大台式机轰隆作响的嘈杂声已经严重影响电脑工作者、游戏玩家以及居家生活的体验，在这个污染源无处不在的生存空间中，人们已经无法承受更多的污染了。迷你主机由于采用无风扇散热设计，整机在运行中可实现 0 噪音，它带给工作和生活的安静体验，已经深受人们喜爱。
The roaring noise of traditional desktop computers has seriously affected the experience of computer workers, game players and home life. In this living space where pollution sources are everywhere, people can no longer afford more pollution. Because of the fanless cooling design, the mini mainframe can achieve zero noise in operation. It brings quiet experience to work and life, and has been loved by people.
The performance of mini hosts has become mature. After several years of exploration and accumulation, most of the mini hosts can meet the basic needs of 70% of users, such as office, entertainment, industrial control, display and play. Although most of the mini hosts are still designed with integrated display, some high configuration and unique Mini hosts are no inferior in overall performance.
Safety and stability
Because of its small size, high integration of main board and compact layout of components and chips, most mini hosts can operate stably for a long time, and it is not easy for individual hardware problems to affect or interrupt the operation of the whole machine, or even damage the whole machine, It is easy to affect the operation of the whole machine due to compatibility or instability of individual components.
Easy to update and maintain
Mini host is small and portable. It is very convenient for software update and hardware update. If you need to expand the memory and hard disk, just use a screwdriver to open the cover of the mini host. The main board architecture and hardware inside the chassis can be seen at a glance, and the replacement is quite convenient. If the host needs to be repaired, girls, children and the elderly can easily take it out of the store or send it back to the manufacturer for repair.
除了英特尔自身的几款微型 PC 价格甚高，其他品牌的迷你主机价格显得十分亲民，一般也在 1000 至 3000 元以内，配置高一点的，价格一般也不会超过 5000 元，这在一定程度上给 DIY 用户腾出了很多预先空间。
In addition to Intel’s own microprocessors, the prices of other brands of microprocessors are very close to the people, generally within 1000-3000 yuan. For those with higher configuration, the prices will not exceed 5000 yuan, which, to a certain extent, frees up a lot of space for DIY users.
Disadvantages of mini host
迷你主机目前的软肋无疑是显卡的问题，众所周知，独显运行发热量大，由于迷你主机生来就是定位于小巧，在控制发热量的时候自然牺牲了主机部分的性能要素，市面上大部分的迷你主机都是采用集成显卡而非独显，原因就在于此。所以，带集显的迷你主机在应对大型枪战游戏的时候会显得有点吃力，当然在小型单机游戏以及播放 1080P 高清视频上是毫无压力的。
The weakness of the mini host is undoubtedly the problem of the graphics card. As we all know, the heat of the single display is large. Because the mini host is born to be small, it naturally sacrifices the performance elements of the host when controlling the heat. Most of the mini hosts in the market use the integrated graphics card instead of the single display. That’s why. Therefore, the mini console with integrated display will have a little difficulty in dealing with large-scale gunfight games. Of course, there is no pressure in playing small stand-alone games and 1080p high-definition video.
Mini host products have after-sales problems, and most of the time, users need to send them back to the factory for repair. Many computer repair shops still can’t provide technicians and technical services for mini host maintenance. Of course, the mini host market has just opened, and after-sales always lags behind product sales. It takes time to accumulate technical services.
散热是一个问题。不管是在软件更新还是硬件更新方面，大部分迷你主机可以实现长时间稳定运行，TDP15W）来举个例，热设计功耗 TDP 一般在 10W-17W 上下。
Heat dissipation is a problem. Whether in software or hardware updates, most mini hosts can achieve long-term stable operation. For example, the thermal design power consumption of TDP is generally about 10w-17w.
随着英特尔大力提倡 NUC（Next Unit of Computing）平台概念，市场中各家品牌的“迷你电脑”逐渐多了起来。通常作为家庭第二部，甚至是第三部电脑主机，迷你电脑更多承载着家庭互联网娱乐终端的重任。相对于传统台式主机，迷你电脑可视作此前 HTPC 概念的进化版，其不仅整合度更高，运算性能更强，同时还拥有更为袖珍的外形尺寸。
With Intel vigorously promoting the concept of NUC (next unit of Computing) platform, there are more and more “mini computers” of various brands in the market. Usually, as the second or even the third home computer host, mini computer is more responsible for home internet entertainment terminal. Compared with the traditional desktop computer, mini computer can be regarded as the evolution version of the previous HTPC concept, which not only has higher integration, stronger computing performance, but also has a more pocket size.
