The Atlas 550 from Antec puts the advanced features of a server case into a smaller package for a home server or power workstation. The 8-drive bays are split between exposed 5.25" (1 has a 3.5" adapter) and internal 3.5" bays with vibration damping grommets. The side panel has thumb screws for easy access, and the front panel comes off to access the drive bays and two 92mm fan mounts.

In addition to the front mounts, the front panel is vented for maximum airflow across all components. For additional cooling, the side panel has a vent with holes to install an 80mm fan over the video card. The back panel has a three-speed 120mm fan to pull air through the system and over the CPU, keeping everything cool.

The TruePower Trio 550W PSU is Certified SLI-ready by NVIDIA with dual PCIe 6-pin connectors. There are also 4 SATA connectors for today’s high speed drives. An Antec case with an Antec PSU is a great foundation for a powerful system.
