While I didn't use the SYS-AZ dawers...I made my own equivalent...and agree. Slide them out, open the box and so forth. Lesser used tools are "bottom" of individual short stacks so rarely will a box need to be physically removed. A drawer for every box is overkill in most cases, but not an issue for me with how I planned things out. I didn't do rolling, however, as that wasn't a good fit for my shop.
