Cold Rolled Steel GPU Mining Rig Frame — Motherboard Case & AirConvect Mining Rack

Built for rigidity: braces are added at both ends of the bracket to create a triangular support, preventing rack distortion and reducing PCI card bending or poor contact caused by insufficient frame strength. Broad GPU compatibility: designed to accommodate multiple graphics cards without limiting their length or height. Effective cooling provision: a rear mounting point for a 12cm fan is provided (installation of the fan depends on graphics card length) to improve airflow. Secure power supply mounting: although the power supply is fastened with only two screws, the plate thickness and reinforced structural design provide sufficient retention.
