Although these three are all nice, the most general and the most standard form factor is usually ATX. If you are looking for a small and compact option then you can definitely go with mini ITX and micro ITX options. Otherwise, the ATX form factor is the most standardized form factor that is widely used in the construction of motherboards.
Ram Storage
RAM stands for Random Access Memory. It lets you store a wide range of information on the motherboard making it more reliable for pro performance. Keeping that in mind and focusing on for what purpose you are purchasing the motherboard, it is very important to finalize the storage you will need.

Expansion Slots And PCI-E Options
Expansion slots allow you to expand your setup and make it better and more premium for whatever purpose you are using it. Looking for a motherboard that comes with PCI-E slots and numerous expansion ports is worth purchasing as compared to one that has limited or no PCI-E slots.
Basically, PCI-E slots are the connectivity slots that add to the works of the motherboard by allowing you to make connections with various external devices such as audio cards, video cards, and graphic cards. Having more PCI-E slots is always recommended because more of them will offer you more options for making connections.
Compatibility
