Hey Brian,
A while ago I bought three 2 space locking rack drawers which I lined with slotted foam sheet. I made drawer dividers out of fiberboard which were also foam covered that slide into the slotted foam.
Two of the drawers have compartment across the front that hold mic clips and accessories. The rest of the drawer is divided into 5 or 6 slots. The third drawer is just foam lined without dividers. The three drawers are contained in a 6 space rack.
After a bit of fiddeling to get the right compartment sizes I have a neat and efficient system to store all 22 mics, two DIs, polarity tester, EWI cable checker and batteries.
I keep all my gear in smaller cases since I have to setup by myself and find them more manageable. Usually I stack the cases on stage, Power Distro, Main Amps, Monitor Amps then Mics. This gives me quick access to everything I need and looks professional since all the cases are identical.
If I can dig up a picture I'll post one.
Ciao
