Love it
Color: Black, Size: Width up to 13.4''
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.

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