IMHO there is no substitute for decent flight casing. And that comes from years of working for HES in the old days (before Richard and I got the heave-ho), and several years of building Catalyst systems for rental.

Simon of SNP Productions sells decent ones:

This style of flightcase, with shockmounted sleeve and then with foam to protect the Macs means that your chances of getting your Catalysts to sight with all the bits intact, and without invalidating your warranty or your cards rattling loose.
