Micro ATX motherboards reduce board height relative to full ATX while supporting mainstream AMD or Intel sockets, memory and expansion in compatible cases.
Choose the CPU platform first, then compare DIMM slots, PCIe spacing, M.2 count, rear I/O, networking, fan headers, front USB and firmware support.

Compact size can reduce extra expansion positions without changing CPU performance by itself.
Match the processor to the physical socket and the board CPU support list. A compatible socket can still need a newer BIOS.
Micro ATX supports fewer positions than ATX, and a thick GPU can block a remaining slot. Check whether a capture or network card still has clearance.
Some value boards provide two DIMM sockets while others use four. Future capacity and attainable memory speed depend on that layout and the controller.
Compact boards can disable a SATA port or change a PCIe slot mode when certain M.2 sockets are occupied. The manual lane table defines the combinations.
Count fan, lighting, USB-C, USB-A and front-audio headers before choosing the case. A front connector remains unused if the board lacks its matching header.
A large graphics card may cover lower slots and internal connectors on a short board.
