Magma ExpressBox 3T- RED is exclusively offered to users of the Classic RED ROCKET and RED ROCKET-X card. The EB3T-RED includes special mounting holes for BNC connectors and the special auxiliary power adapter required for the RED ROCKET. This allows the use of a RED ROCKET card without the need for the BNC connector bracket that would normally occupy a valuable PCIe slot. The perfect chassis for RED users.
