Laptop storage with charging and networking

Hi,

At any given time I have between 10 to 20 laptops that are pre-staged and ready for use that need to be powered on and on the network at all times for patches and updates. In the past I had a wall of shelves with chargers and network cables running all over the place and I’m looking for a better solution. Almost all of the laptops are full size Dell’s. I’m kicking around the idea of getting a 4 post server rack with no sides, putting a shelf in every other or every third slot for each laptop. A 24 port switch and a rack mount usb charging hub. I’d like to hear how others have handled similar setups and the hardware they used.

Thanks
