Emissivity of powder coated steel

Q. Hi there,
I try to install a thermal camera to control the temperature development in a computer housing during work. The housing is light grey powder coated steel. In order to check the heat development during work, I need to set the emissivity of the housing for precise temperature measurements. Since I didn't find suitable values in the literature, can anyone help?
Thanks a lot!
