There were 4 "Y" parts- not labeled and it was not possible to determine which attached to D and which attached to C. Also steps 22 and 23 both showed that F was attached to both the drawers and computer cabinet - not true. The problem is that step 23 mislabeled the backboard. Also, part G on step 21 was unclear- it depends on which side of F you are working on. Finally, screws H39558 did not exactly match the size depicted on step 12 so I had to go to the hardware store and buy the correct size. Turned out that the screws enclosed would have done the job but I was one screw short.
Two of the large wood pieces were not labeled.
"A"and "B" did not fit well to to the backing boards and need some severe hammering to fit.
