I moved from a 20" imac to a 24" imac. Anyone find that the 24" monitor height is too high? I need to lower it about 2-3 inches. The only option I found is a VESA mount Ergotron 33-329-057 neoflex widescreen monitor stand. The shorter 20" imac and 24" cinema display stands do not fit or support the weight. Anyone have experience with this mount? How does it look with the Aluminum imac? Any other suggestions
