Hi, can somebody help me with this? I'm thinking about buying a Fafner, but I'm a bit worried about the fact that the cooling-fan is on the side. I have have a 4U SKB rack-case wich can be opened from the front or back, and not from the sides as usual. Will that 1U rack space wich is left(the fafner is 3U) be enough to provide the amp from cool air?? Or do I have to make holes in my case or something?? Will a 1U ventilation panel help??
