The case is sturdy but the constructioninstallation instructions are terrible!  So, I am here to give some advice to those who do not assemble these things for a living!  

First, at the very beginning make certain that you keep the 2 side panels, Numbers 3 and 4 always on the correct side.  You must always have the number 3 panel on the left, and number 4 panel on the right.  I recommend numbering each panel with a pencil on the inside.  Before attaching the top and bottom, double check to ensure the side panels will be 3-left side, 4-right! The rest of the assembly of the empty-cabinet is straight forward!
Second, the next area that caused copious cussing was the installation of the front drawers.  They all look exactly the same, however the placement of the hinges is not the same on all three.before the begin installing them, measure the distance from the top of the door to the hinge, you will see that two hinges are placed(You can also just eyeball it)
