I was in contact with Joe about this as well. As paskowitz said, theyre looking to buy the top covers in bulk and just supply a whole new modded cover. So with this I figured I'd at least take my own attempt at doing a vent mod, and it turned out decent I think. I simply cut a hole to size with a jigsaw, filed it down, and then sanded a silverstone fan filter to fit. I just bought the evolv and it was my first attempt at any kind of case modding, I painted the interior as well. Overall I'm just glad i didnt totally destroy this case pics below
Wow dude you did great! well done.
