The Fourth Dimension!
In addition to Length, Width and Depth there is another dimension that you should consider when purchasing equipment cases, The Diagonal Length! Keep in mind that the diagonal length (lower right hand corner to the upper left hand corner and vice versa) exceeds the width and height. It's a "math" thing but the diagonal length of any case can be easily determined by any online rectangle calculator. You can easily fit many items you wouldn't think could fit into this case.
Example: The SKB 3I-1610-5B-C dimensions are 16" wide x 10" long x 5-1/2 deep. The "diagonal length" of this case is almost 19 inches (18.868" to be exact!) . Any shotgun mic up to 18 inches will fit comfortably in this case with room to spare for accessories. Something to ponder when buying any case.
