Which component is likely to cause issues if the motherboard supports a different form factor than the case?

When considering the compatibility between a motherboard and a computer case, the physical fit of the motherboard is crucial. A motherboard comes in specific form factors, such as ATX, MicroATX, or Mini-ITX, which dictate its dimensions and the layout of components. If the case is designed to accommodate a different form factor than the motherboard, the motherboard may not fit properly or at all.

For instance, if a case designed for Mini-ITX is paired with a standard ATX motherboard, the motherboard will be too large for the case, preventing the installation of the motherboard. This can lead to significant challenges during the assembly of the computer, as the mounting points for the screws and the I/O shield might not align correctly. Ensuring that both the motherboard and the case match in terms of form factor is critical to achieving a successful build.

While other components, such as the processor, power supply, and RAM, are important for overall compatibility and performance, they are less likely to directly affect the physical installation process compared to the actual dimensions and mounting characteristics of the motherboard itself.
