Casters would have been nice. I love the concept though. I have a small, but powerful pa system, mackie profx12 rack mounted in the top, a couple behringer EQ's, ART dual digital surge protector, and 2 QSC GX7 power amps. I get to a gig, set speakers up, pop the covers on this rack, connect speaker wires, and Im up and running in about 10 minutes. Pretty freakin Cool!!
