I'm using this with an Asus Prime micro-ATX case on a sit/stand desk, and it works beautifully. It's expandable, so it would have no trouble with a full ATX case. The PC is well supported and there is no wobble whatsoever even when the desk is moving between sitting and standing positions. Highly recommended.

Great computer mount but was missing some parts
