Sumo 5115, the masterpiece of GIGABYTE chassis, catches your attention with its sleek aluminum panel design. Like its predecessor Sumo 4192, the all aluminum Sumo 5115 is compatible with water cooling systems right out of the box. It is designed for maximum system cooling while maintaining quiet operating parameters - so while there are no less than three large 120mm cooling fans in this case, they all run without really being noticeable. Best of all, it has two tubing pass through vents for water cooling systems.
