As a result, the power supply and hard drives can be discreetly installed on the underside, out of direct sight. Additionally, the S1000 features a practical cable management system that allows for clean wiring of all components through numerous openings and cutouts, simultaneously optimizing airflow inside. The tunnel is designed to accommodate a power supply with a maximum length of 20 cm right out of the box. The movable hard drive cage expands the mounting space and can be shifted up to four centimeters towards the front panel using thumb screws, for instance, to accommodate extra-long power supplies or to provide more space for cabling. Graphics cards can be mounted with a maximum length of 40 cm, and CPU coolers with a maximum height of 15.5 cm. Two 120-mm fans are pre-installed upon delivery: one fan is located behind the side air inlets of the front panel for fresh air intake, and another fan is mounted at the back. A dust filter protects against contamination and can be quickly removed and cleaned thanks to its magnetic attachment. Easily accessible and removable dust filters are located at the front and on the underside at the power supply air inlet. 3.5-inch hard drives can be comfortably mounted without screws on a rail system within the tunnel on the underside. Air circulation is enhanced by ventilation slots integrated into the tunnel. Two SSDs can be accommodated on the back of the motherboard tray. A drive bay for 5.25-inch drives is available, which alternatively also allows for the installation of two additional SSDs.
