ASUS Prime B760M-A-CSM Intel B760 (LGA 1700) mATX CSM Commercial Motherboard PCIe 4.0, DDR5, 2X M.2, 2.5Gb LAN, DP, 2X HDMI™, SATA 6 Gbps, USB 3.2 Type-C, Aura Sync, ASUS Control Center Express
For this build I wanted a modern, stable micro-ATX platform that still gives me the basics I care about for a VM host: solid I/O, M.2 support, and a straightforward layout. The ASUS Prime B760M-A-CSM fits the rackmount plan without forcing me into a huge board, and it keeps the build practical for a home lab.
