MSI PRO B860M-B

This is an Micro-ATX board on the B860M chipset, LGA1851 socket. Expansion covers 2 M.2 slots and 2 PCIe slots. Memory support covers 2 DDR5 slots up to 128GB total. Pick the board for its socket before anything else — chipset niceties come after.

Its $149.99 price tag places it squarely in mid-range territory. Use the PlanMyPC system builder to verify it works alongside your other components and to keep a running tally of the cost.
