Explanation:

The sound card is installed between the back side of the system case and the motherboard's ports to handle audio - related functions. A head - speaker is a peripheral connected to the audio output, not installed in that location. A floppy disk drive has its own slot and connection. A fan is for cooling and has different installation positions related to airflow, not this specific location for audio - related installation.
