With the Silencio S600 Steel, Cooler Master presents a no-frills midi tower featuring pre-installed noise insulation and a customizable interior. Its sleek and modern design fits well into any setup. The interior provides ample space for powerful hardware and good ventilation. Up to five case fans can be installed in the Cooler Master Silencio S600 Steel. You can mount 120-millimeter fans on the back and two 120- or 140-millimeter fans on the front. There is space on the lid for a 120 or 140 model, and by removing the 5.25-inch bay, a second fan can be attached to the case lid. The Silencio S600 Steel comes with two pre-installed Silencio FP silent fans in 120 millimeter format, controlled via PWM signal. The case accommodates CPU coolers with a maximum height of 167 millimeters.

The Cooler Master Silencio S600 Steel also provides options for installing custom and complete water cooling systems. A 120-millimeter radiator can be attached to the rear panel, while the front is prepared for a 240- or 280-millimeter radiator. On the lid, there is space for a 120- or 140-millimeter radiator. If the 5.25-inch cage is omitted, a 240 dual radiator can also be installed there. This no-frills case features clear shapes and smooth surfaces, completely black on the inside and outside. Designed for low operating noise, the midi tower is equipped with extensive vinyl and foam noise insulation that dampens vibrations and sound. Both the steel side panels and front door are internally insulated. The lid has a removable cover for improved ventilation. Dust filters are located in the front, base, and lid. The front door can be mounted with hinges on either the left or right side, allowing it to swing in the desired direction when opened. The I/O panel is located on the right side of the case lid and includes two USB 3.0 ports, a combined audio port, and an SD card reader.
