best practice for employee directory, not all employees are computer users

I'd like to make an employee directory with names, pictures, phone extension, etc. I was also planning to use this as as a lookup column in several other custom lists, to track other information related to that employee.

I am wondering, however, if it would be better to use SharePoint's built-in user profiles (ours sync with Active Directory). The problem is that not all of our employees are computer users, and often an employee that hasn't been a computer user will need an account created.

Is making a custom list the best way to go, or is there some way that I can use SharePoint's built in user profiles? I'm using SharePoint 2007.
