I am using nested matrices, but this is one case which will be best solved by something equivalent for gathered and aligned. It has been on my todo list for a long time.
Here is a solution using nested matrices, where I use \noalign to fake correct spacing after the first line (and changed the \cdots in the last condition to \dots).
\definemathmatrix[rightbrace][left={\left.},right={\,\right\}},n=1,align=left]

Great, thanks a lot! And is there any way how to get in the first line \min_{x \in X} with the parameter exactly below the "min"? Because in this solution the parameter {x \in X} is on the right bottom, like in a line. Czenek

Add style=\displaystyle as an option in the definition of rightbrace. Aditya
