The modular Type-4 connections let the builder attach the cables needed for the configuration. A native PCIe 12V-2x6 GPU cable is included for a compatible graphics card. The unit measures 160 × 150 × 86 mm.

Cooling uses a 140 mm fan with Zero RPM mode at low to medium loads. A manual fan override knob provides a way to increase fan speed and airflow when desired.
