My situation is a bit different than most. I work in a big cabinet shop, so the large machines are shared. The space under the table saws has storage for off-cuts or project parts that are more universal.
I keep my Systainers in cabinets similar to what you are describing, but they are all in a line, instead of wrapping around an outfeed table. My "Sysports" are not portable at all
The point is more about how they are arranged. You mentioned storing them in groups of similar items, but I don't really do it that way. The sanders are all in one column, pretty much right down the middle of the row. Everything else is arranged by convenience. In general, that means the items that are used to most or that have a lot of small parts are near the top. The TS55 is an exception. It is near the bottom of one column, even though it gets used very frequently. It is on the end nearest the cutting station and as a large tool that gets drawn out of a deep Systainer, it is easier down low. It sort of works out that they stack largest to smallest. The CSX, clamping elements/dogs, PS420 and router bit case are at the top. The TS55, TS75, and OF1400 are at the bottom. The OF1010, Domino, etc run through the middle.
I don't "go get" things, they are all right behind me as I stand at the assembly table, used as needed and put right back away. This is the beauty of the system as it works for me, they are arranged by how I use them, rather than what they are. Mine were built on the 32mm spacing and 5 sizes of the T-loc generation though and taller than most, way too tall for an outfeed table.
Although I am in a static/stationary situation, if I need to, they can be stacked up on the CT26 and taken anywhere.
It's just a different way of storage and way of use that might help someone.
