It was a pretty simple project actually. I didn't design the faceplate though. I grabbed that from thingiverse. The only hardware that touches the HMD is a torx head screwdriver to remove 4 screws. The 5volt 40mm fan can be attached to the USB plug in a few minutes after stripping some wires and soldering them together. I'm happy with the current state of things, but if I change my mind it's a matter of taking out those 4 screws again to put the original faceplate back in.
