Is that the wide angle model with the short rail? Do you want a hard or soft case & how many holders & other accoutrements do you want the case to hold? If yours is a short rail, take a look at an Igloo Playmate (no, really!) They are tough and the appearance deters bandits. If the ID is long enough to accomodate the rail, make two partitions(plywood is good) or a smaller box to fit inside with the edges notches to hold the rail with the camera upside down between the partitions. You should have plenty of room for your dark cloth, holders, filters, loupe, meter, etc...
