Board on top of computer desk drawers blocking 2 cam locks because incorrectly installed upside down. Smashing and removing board cause instability?
Just rotating the cam locks should allow you to remove the top, they don't have to be pulled out to release the cam-lock post on the top.. You could use a thin slotted screwdriver to rotate them even though they are blocked from removal. Then take off the top and when you put it back together make sure you do not make the same mistake.
