When searching for a micro-ATX case, consider factors such as size, airflow, and aesthetics. Micro-ATX cases are compact and space-saving, making them ideal for smaller builds or limited spaces. Ensure the case has adequate airflow to prevent overheating components. Consider the case's design and appearance to match your personal preferences and the overall build theme. Additionally, check for features like cable management options, dust filters, and front panel connectivity for convenience and ease of use.
