Great computer mount but was missing some parts

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.

This is a solid piece of kit. Very sturdy pieces of steel,
Color: Black, Size: Width up to 13.4''
Many options for configuration, the only thing is double check your measurements. Mine ended up just not deep enough to use it with the current desk. I have. Waiting for an updated desktop. With a sit stand desk. The bar across the middle cuts your distance in half and the purpose of buying this is because you got a big computer. Double check your measurements

Decent budget option, difficult to adjust once set up
Color: Black, Size: Width up to 13.4''
Not bad and serves it's purpose. There are better options for a few more bucks, but this one is holding very well for the price.

IT HOLDS!
Color: Black, Size: Width up to 13.4''
Heavy duty set. My desktop weighs about 60lbs, and I’m surprised how well it’s being held. I’ve always had my desktop on top of my desk. But it feels so much more roomier not having it on top of my desk. On top of that during this cold weather it’s like having a heater under my desk. Of course my desktop is gaming wise. But if you are someone with just a standard browsing desktop then it shouldn’t be hot down there. Make sure your desk is real wood or thick metal. If it’s an ikea table and the basic kind where it looks like wood, but it’s actually cardboard inside then for sure it’s gonna snap off, and that wouldn’t be pc mounts problem, rather a desk type issue.
