Here's the back! I haven't had to cut anything from the case!. Currently ethernet connects inside because I haven't got the PCI Ethernet slot working in macOS yet. The travel 4 port USB 3 hub is also connected inside and its not ideal, I had to remove the rear fan guard to plug it in. Maybe it will fit inside the top PCI slot. But I'm getting a right angle USB3 extension cable to tidy it up. Eventually all the cables will go through the power port and connect inside.
