Roel,
I thought about adding a metal bar.
Yours looks like the lightweight ones used in pairs to support shelves on the wall.
Is that right?

Also, cutting the drawer like that, doesn't it leave the middle of the keyboard without a place to sit on? Mine has one little rubber "button" in the middle, under the keyboard, as well as the ones in the corners.
