thank you for the screenshot, but I see that it seems a standard PC (core i5, 4GB ram, more than 200GB HD).
With thin client I mean a little hardware that can run virtualized desktops (such as VMware Horizon), something like this: HP t420 Thin Client | HP® Official Site
I don't have any type of this hardware in my company.
Beware as thin clients are not supported (sea ideas here). Anyways, as long as the thin client has wmi and that the attributes we gather by default exist on the device then we'll be able to gather the same. If what you are looking for is in a different attribute than in the default one, then you'll have to customize your hardware inventory filter so it gathers these attributes.
I am sorry but I havn't had a chance to work with thin clients and I don't know much about it so...
