The Office Deployment Tool (ODT) is a command-line tool that anyone can utilize to download and deploy Click-to-Run versions of Office to compatible devices on the network. To locate the tool, query 49117 on microsoft.com.
I use it mainly with my custom Configutation.xml from the Command Prompt so that I can do multiple systems (two desktops or four laptops to limit overloading the power strip) at a time. On a system with SSD and at least 16 GB of RAM, you could do an install as quickly as six minutes giving you the opportunity to do ten systems an hour.
