Arg, the assembly instructions had a few mistakes, so it took longer to assemble.  Some of our corners and sides do not match up.  And, yep, we do have the correct pieces.
We have drawers and doors that are crooked.  We had screws break off while we we screwed them in.  The front of one of our file cabinet drawers already fill off (used it maybe three times,) and we used the screws we were instructed to use. One of our inside file drawers was not scored for the bottom piece to fit into it.  
etc. . . . 
I would not recommend this cabinet.  Not sure it will last much longer without falling apart.
