The dimension of the whole desk is : 50.8" (L) x 50.8"(L) x 28"(H); The dimension of the monitor stand is: 18.9"(L) x 7.8"(W) x 7.2"(H). The width of the desk board is 18.1 inch.
Does that mini stand rising come off?
Yes... you do not have to attach it if you so desire not to.
Can i take the corner out and make it like stright instead of a L shap?
Yes, you can take the corner out and push the two straight sections together. I got 2 of these to put together as a U shape in my craft room to hold some of my machines. Together they were to big for the space, so we took a straight section out and use it as a free standing table.
which is the exact size in the box?
The desk is exactly at described. Each side 51 inches from edge to center. It's very good space.
