Welcome to Bleeping Computer.
You can't get an apples to apples comparison, even if the companies are the same size. Computer specifications will depend on the type of users you have.
I work for a global company and there are basically four standard machines: standard laptop, engineering laptops, standard desktop, engineering desktop. I say engineering because that's normally who would get that type of machine, for CAD programs. However I have people who work with databases who need the more powerful machines to run their queries.
So, you need to make a determination of what types of machines your users need. Try to minimize the number of machines you authorize for the environment. If people aren't allowed, or able, to work remotely go with desktops to save money.
In business you buy machines, you don't build. Both HP and Dell business lines have next day on site support for hardware failures, accidental damage is extra. This allows you to standardize your environment. The fewer variables you have the better life is.
Network printers ONLY. Most network printers can be configured with a secure print option where you have to put in a code to get your print job. That's for the user who says I need a personal printer because I print confidential information. Standardize your printers also, the fewer supplies you need to stock, the better.
