How can I check through command-line the computer form(Desktop, notebook
or All-in-one)?

For a very specific reason I need to check the computer form
factor(Desktop, Notebook or All-in-one) remotelly, using a command through
the command-prompt, powershell or vbs(Windows 7/8 systems).
There is any way to do such thing?
Thanks in advance.
