I need to rack mount my 4pro amp. The problem I am having is finding a rack with enough clearance on the sides to ventilate the head properly. I was thinking if nothing else I could drill some holes in the case for ventilation. The ones I was looking at last night at GC all had the handles on the sides right where the vent holes would need to be placed. Handles would be nice to have on a 5 or 6 space rack. Any suggestions? Should I have a rack custom made? I was looking at Caseman last night. I really would rather not spend that much. The Gator G shock looked like it might work. Reasonable price wise but I can't seem to find a 6 space. Thanks for your time.
