Review on 1U 19 Inch Rack Mount Server Shelf Cantilever Tray with Vented Shelves - 6 Inch (150mm) Depth by Raising Electronics by Lawrence George

Great shelf for networking equipment etc. Would like to see the front curve go up instead of down. It's hard to tell from the picture, but the curve at the front takes away from the overall height. That means if the equipment you need to attach is about 1U high, you need to leave 1U of free space above it. If you have a room this isn't a problem, but for those with space constraints it might be.
