Anyone have an idea how to put 3x 120mm fans im front of Thermaltake XT20? The manual say it suport that configuration but the bracket in the front says he won't because there is to big hole in it to screw it in? I mean the top fan, there is a space for 2 of them. The good thing is i have Lian Li fans that connect to each other but it won't be so stable as it should. Anyone can help?
