Mine feels pretty F'ing sturdy.
The only real issue I have so far seems to be with the keyboard drawer in that it just feels cheap. I'm going to reinforce it with some gorilla glue to keep the cam from popping out (again and again).
Additionally, they have a panel on the back (not sure, think it may be K) that they want you to wood screw in. I looked at it and immediately thought "This is RETARDED!" so, instead, I went and got some black velcro and placed it on the two support boards. Dropped in a little stylish knob (Menards, maybe $2) and now I have a secured door that I can at least take on/off a little easier.
A note on that, however--the cam for one of those supports popped on me and I'm gorilla gluing it, to. I was going to hinge that panel, but given the angle and my incompetency, the whole velcro route works pretty well.
