台式机硬件三连发，前文我们提到了固态硬盘 PCIE 转接器，老的固态哪里去了呢？当然没有浪费，有没有坏掉，拆下来安装到了新买的机械师创物者Mini-3765H上（一年前）。
新机器，硬件规格还是给力的，2.5G 双网口、PCIE4.0、WiFi6。
最近搬家了房间没有单独的路由器组网，机器都是走无线网络连接，华硕主板台式机的无线网卡性能不太行，也可能是路由器无线接入，局域网之间上传速度不行，导致机器之间的网速不太行。新购买 2.5G 网卡，安装到台式机上。
至此，主板的插槽用完了：显卡、无线网卡、2.5G 网卡、固态硬盘 PCIE 转接器。
网络说明
两台机器上网还是靠原本的无线网卡，但是两台之间走网线直连，两端都是 2.5G 网卡。怎么网线直连两台机器，这里就不多说明了，网上有很多教程，记得放开防火墙。任选一台作为网关即可。
