Well - the 408 MLX should fit - whether a Legend or Magix version. If it's a Legend - it will obviously be missing the Magix grey front piece - and there will be no (easy) way to lock it into place.
The old style Legend 800 DID will not fit - because it is a 2-piece Legend board (too tall to fit in a Magix case).
