Chassis for ATX motherboards

The Supermicro CSE-523L-505B is a black 2U rackmount server chassis that accepts ATX boards up to 12" x 10". It ships with a 500W 80 Plus Platinum power supply operating at 93 percent efficiency across 100-240V AC input at 50-60 Hz.

Seven low-profile expansion slots

The chassis provides seven low-profile expansion slots, which is the limiting factor for add-in cards. Full-height cards will not fit, so only low-profile or half-height adapters can be installed.

Two fixed 3.5-inch bays

Two fixed 3.5-inch drive bays are included, with an optional configuration supporting up to four 2.5-inch drives. A slim DVD-ROM bay is also optional, while dual hot-swap 80mm exhaust fans and an air shroud handle airflow. Builders needing more internal storage or full-height cards should look elsewhere.
