Awesome desk design, good finish, well built.  Even though they are hollow, but the built is solid and sturdy.
Just minus one star on the installation about the long screws that goes across the pieces.  It's rather difficult to align it just right to make it go through.  Become easier after going through 4-5 of them, but the first couple of them took a while to finally get it through.

After all, it's a beautiful desk after installation and I love it.
