Keep compact business systems running in a chassis built for straightforward integration and dependable serviceability. The In Win EFS052 Mini Tower Chassis pairs Micro ATX support with a 450 W power supply already installed, reducing sourcing complexity for refresh projects and small-form-factor deployments. This enclosure is designed for environments that still depend on optical media, legacy peripherals, or mixed storage requirements. It provides 2 external 5.25-inch bays, 1 external 3.5-inch bay, 3 internal 3.5-inch bays, and 1 internal 2.5-inch bay, giving IT teams flexibility to balance capacity and compatibility. Four expansion slots support add-in cards where a slim desktop cannot. Front I/O includes 2 USB ports and separate audio in/out connections, while support for rear and front 90 mm fans helps maintain airflow in a compact footprint. At 13.8 inches high, 6.7 inches wide, and 14.1 inches deep, it fits neatly into constrained work areas without sacrificing the essentials. RoHS compliance and a 3-year warranty add confidence for procurement teams standardizing on a durable, serviceable chassis.
