    I just ordered this unit. I plan to run it externally and then pass the 4 PCIe cables through an open PCI slot. It's designed to fit into an optical drive bay, but mine are full.

    Be advised that it needs a 4-pin molex signal to switch on and off. The molex doesn't draw power, but it's used to switch the PSU on simultaneously with the main power.
