I messaged him last night on his site asking about prices and he replied within a few hours.
Names Rik, had a nice exchange but he's not sure he wants to make it a product because the warranty issue would be too complicated, since it voids Fractal's warranty and he can't fix their components if anything goes wrong later.
He might be willing to make me one if I was located near him, but he lives in Belgium and I don't
. I didn't press him on pricing.
I'd just be happy if there was an FM3 with more buttons. Yes I've used the OMG9 setup but its not what I need.
