A:Answer Thank you for your question. Case designs vary, and in this particular model, the top-mounted ports and vents are part of its intended layout for accessibility and airflow. Like all PCs, regular cleaning is recommended to prevent dust buildup, especially depending on your environment. As with any electronic device, it's important to avoid placing liquids near or on the system since it is not intended to be a place holder for liquids, this case is not water-resistant, and exposure to spills could result in damage.
