When I first booted the computer it asked if it was going to a kiosk or authorized user mode.  Like a corporate computer setup.  I eventually found that if I went to the kiosk selection and let the setup reject my personal account, it would give me an option to sign in with a personal account.  Once that was done the chromebox was fantastic.  Very fast compared to a chromebook.  With a terabyte SSA drive attached, it is a very nice desktop computer.
