mi-d.cn is the 米多贝克&米多网络工程 NAS/server and Synology/Xpenology resource site, "dedicated to solving problems around users." It provides product documentation for custom motherboards, NAS/server cases, finished NAS/server systems, USB boot drives, managed network switches, USB expansion devices, and PCIe expansion cards.

The site also organizes Xpenology software and hardware selection notes, compatibility lists, RR/ARPL boot loader guidance, and DSM model recommendations. Access is mainly through website tutorials, download pages, and store purchase links.

The material is aimed at hardware-oriented users: CPU, motherboard, network card, SATA/SAS/NVME drivers, and boot loader versions need to be checked by the user. The guide clearly advises against very old hardware, many branded PCs, and some motherboards after Intel 9th generation; AMD GPU support is limited, and important data should be backed up before installation.
