Pros: The performance is not bad at all, it's worth $680. Although small in size, there is no shortage of functions. The rest is the function of the computer. There are two pcie 3 m2 interfaces, one m2 2242/80/110, the other m2 2242/80, and two lan ports. The latest ax200 wifi6 wireless network card is a very good choice for soft routing. The built-in power supply supports 500w power supply, and one pcie slot can support up to gtx2070 dedicated graphics card or 10 Gigabit network card to connect to pcie. With HDMI interface, there are two Thunderbolt 3 interfaces, Thunderbolt 3 can power the c-type display and display images, as long as you have a c-type display, it is only supported after installing the system, and it supports the latest windows 11. The appearance is cool and the internal space utilization It is very high and the fan is very quiet. It is very worthwhile to buy such a cool intel computer for $680.Disadvantages: This machine has no memory and hard disk, it needs to be purchased separately, which is also an additional cost. Self-installation requires a certain amount of hands-on ability, you must read the manual, otherwise you don't know how to install it. Hard disks with SATA ports are not supported. The graphics card needs to purchase a specific mini graphics card, otherwise the space is not enough.
