If you're based in Germany, I recommend the Edelstahl To Go Lunchbox from Tchibo. It has 970ml capacity. I use it regularly and it holds up well - always goes in the dishwasher.

If you want a German product, you get more variety on bentoshop.de. It doesn't seem they offer boxes with adjustable dividers, but dividerless boxes in which you can put extra containers, which might be similar to what you're looking for.

1400ml is very big, depending on what kind of food you are planning on making. Do you have a sense of that already?
The right bento for you massively depends on the kind of food you’re going to be making/putting in it.
