CSCS have now launched a new method to deploy new computers remotely. The goal is that a device should be delivered straight from Dell in the box and will be automatically set up for the end user once turned on and signed in to.
All the documents relating to this system, called Intune, are located under this page.
If you have received a brand new Dell computer, follow this guide - New Computer
If you have a device that was previously set up, follow this guide - Joining your existing device
