When installing hardware upgrades, why is it important to consider form factors?

Different processors require different power sources
Form factors dictate compatibility with cases and motherboards
Hardware upgrades can only occur in modular systems
Form factors affect software performance

The correct answer is: Form factors dictate compatibility with cases and motherboards

Considering form factors is crucial when installing hardware upgrades because form factors define the physical specifications and dimensions of hardware components, which directly impact their compatibility with cases and motherboards. Each form factor has specific size constraints and layout features, which means that a motherboard designed for one form factor may not fit properly in a case designed for a different one, or may not connect correctly with the other hardware. For instance, if a user attempts to install a motherboard designed for the ATX form factor into a case that only supports Micro-ATX components, it would neither fit properly nor align with the necessary mounting points and ports. Additionally, power supply compatibility and expansion slot positioning are also influenced by the form factor chosen. Thus, recognizing and adhering to the appropriate form factor ensures that the installed components will work together seamlessly and fit within the physical confines of the user's system.
