One of the back panels was oversize which means I had to saw it down to be able to get the two parts of the rack to fit together.  It was a problem but in the end the rack got constructed and looks nice.  The assembly (except for the problem) was simple and clear though the screwing did take some effort since I don't have an electric screwdriver.  The screw package though was made of brittle plastic and some of the screws were loose but they were recovered,
