The difficult part is the joining of another 2 pieces of wood at the bottom.  That would mean either to screw right thru the back to the front (wood thickness is around 1.5") and trying to do another screw from front to back - I actually broke the screwhead while trying to do this (the wood is really hard). 

I opted for the black metal L-angle as it gives is a nice contrast to the wood.  All woody was too much for me.
