Good Sized Cable Management Tray
Size: 36"
Well made and sizeable cable management system. Pretty easy to assemble and install. The cable tray attaches under the desk/table top with two bracket and associated screws. You'll need about 4 " - 6" clear from the back edge on the under side of the top to make this work. Has a metal plate in the bottom of the netting for setting a power strip.

Sturdy - Easily Adjustable - Works as Advertised
I modified it to fit a small subwoofer under my desk. I flipped the arms, inverted them and screwed it on to the desk. Not the intended use, but it solved my issue perfectly. It's really sturdy, it'll be perfect for mini PC's.
