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.

Amazing mounts my gaming rig under my desk so that I can move it up and down without worrying about cables and such also makes the cable management a lot easier.

Great computer mount but was missing some parts

Color: Black, Size: Width up to 13.4''

Works great but was short 1 machine screw, and had no wood screw for attachment to the desk. The brackets them self are great.

Simple, sturdy and looks great! This is exactly what I was looking for that actually fit my very large PC case. Works well with an UpLift standing desk.
