Cooler Master case MasterBox E501L
The MasterBox E501L
The MasterBox E501L is the essential solution for optimized cooling. A gradient of perforations below the ODD allow fresh air into the system for both air-cooled and liquid cooled configurations. The glossy, colored accent around the front panel compliments the ventilated area.
For simple tasks, the E501L is a cost-effective solution to professional computing. For higher-demand tasks, the E501L can be upgraded to house liquid cooling with enough clearance for the longest, widest graphics cards.
- Patterned Ventilation – A gradient of perforations provide fresh air to cool the system as both a functional and aesthetic design element.
- Highlighted Accent – A glossy, colored accent outlines the front panel, complementing the ventilated area.
- Cooling Support – Support for a total of 3 fans and front and rear water cooling ensure a high capacity for thermal performance.
- Clean Routing Space – There is 19~27mm width of space behind the motherboard tray to efficiently manage and organize cables.
- Versatile Component Support – Clearances of 410mm for the graphics card, 165mm for CPU coolers, and 200mm for PSUs offer room for powerful builds and future upgrades.
