In the meantime, I know more than you do: Two single drawers and two multi-drawers are included. Additional ones are NOT available directly from the manufacturer, but from e.g. Steg, Amazon etc. at

Unfortunately, we do not carry these adapters in our range and, according to the supplier, none are included. These would have to be purchased directly https://www.fractal-design.com/de...
