I have just purchased a new 400+ and am loving it. My problem is in finding a suitable rack case. I have tried the SKB and Gator cases but their sides go inwards to allow for the handles and obstruct ease of ventilation for the 400+'s side mounted fan. I do not want a shock case as I am trying to keep the overall weight as light as possible (I sold my SVT2 for this reason). I also want to keep it physically as small as possible. I am now contemplating getting the 4 unit SKB case and drilling some rather large ventilation holes in the top and on the side next to the fan.Alternatively I could cut out a piece and fit a perforated steel sheet, I suppose. Can anyone think of any problems with this approach? How have other 400 owners solved this problem?
