gnome-terminal border
 

I would like to remove it in order just to see nothing else than the text

anyone knows how to do that?

I believe this depends on your window manager. If you are running Gnome with Sawfish, I think Sawfish has the option of what border style you want if you right click on the title bar. I am not sure on this. I don't use Sawfish myself. Someone else my know exactly.
