Premium Aluminum Paneling – The top & front of the case are clad in anodized aluminum with a smooth s&-blasted finish. Vertical Chimney Effect Layout – With the 200mm fans that intake air from the bottom, hot air rises out of the case & exits out of the top in a natural direction for efficient thermal performance. Noise Reduction Technology – The design of the panels address noise reduction by inhibiting noise from escaping toward the individual. The 2x 200mm fans operate quietly in comparison to the volume of air they move & can operate even quieter by manually controlling the fan speed slider found on the I/O panel. Rotatable PCI Bracket Window – The PCI mounting window can be rotated 90 degrees. This allows the unique ability of mounting graphics card (s) vertically or with more clearance from the glass side panel. *riser cable not included Versatile Storage Brackets – The SL600M has versatile brackets that can mount an SSD, HDD, a water pump, or reservoir. These brackets can be placed in multiple positions inside the case, including being placed behind the front panel & on the bottom radiator bracket Advanced I/O Panel – A proximity sensor triggers the USB (Universal Serial Bus) lighting for easy access in the dark.
