Border-less windows for Gnome

I have searched long & far for a way or program to get rid of the window's borders on Gnome, mimicking the look Os X has.
I have found Devil's Pie, but it removes all the borders.
So, I tried editing the 'metacity-theme-1.xml' file for the theme I'm using right now Unified.

Edited these lines:


distance name="left_width" value="0"/
distance name="right_width" value="0"/
distance name="bottom_height" value="0"/


Set all the values to zero, and presto.
The thing works best with the gnome-terminal having a black background.
I have also edited the same file, before this one, to get rid of the roundered corners on the bottom of the screen.
