Now that I have acquired rack gear over time, I need a equipment rack case. Gator? Skb? ATA? My problem with custom design is that the gear is always changing right? So I think I would need generic. And since I need at least 14 single space slots; would one get 2 smaller roller cases like a suitcase with pull handle. Or one of those big caster wheeled ones knowing the thing would be about 100 lbs or more. Does one worry about heat within the rack? Other thoughts as well welcomed. I do local stuff about 5x per year.
