Report of all laptops that have not connected in 90 days?

I am attempting to get a report from my SEPM that will list all laptops that have not connected to the SEPM in "X" number of days.

I did not see anything within the console that would get me the data I need, so I was hoping that somewhere in the SEPM database the Chassis Type was stored. I've checked SEM_COMPUTER, SEM_OS_INFO and a handful of other tables... sadly no joy. Does anyone know if chassis type is somewhere hidden in the SEPM DB?

Thanks for any suggestions.
