What they have in Common
same graphics cards
IF the motherboard has a PCI-Express x 16 slot AND the graphics card is able to fit into the computer case. However, high-end graphics cards tend to be massive so most Mini-ITX cases (and some MicroATX ones) won't have enough space to accommodate these behemoths.
back panel ports are similar
The space taken up by back panel ports and connectors on a motherboard is about the same regardless of its size. Rather, the number and type of back panel ports on a motherboard are influenced by its price
same CPU
As long as they are of the same generation, all three form factors will have the same CPU socket.
