With the compact S1000, a micro-ATX case incorporates a tunnel for the very first time. As a result, the power supply and hard drives can install discreetly to the case bottom and out of sight. Additionally, the S1000 has a practical cable management system, which allows for orderly cabling of all components via its numerous openings and recesses, while simultaneously ensuring optimal airflow inside the case. The tunnel offers enough space for a power supply with a maximum length of 24 cm. The expanded installation space allows the mobile HDD cage, which secures via thumbscrews, to be moved up to four centimeters in the direction of the front panel, for example, for extra-long power supplies or if more space for cabling is required. Maximum length of graphics cards is up to 40 cm. Maximum height of CPU coolers is up to 15.5 cm.
