You'll just need to include the WMI call to grab the machine model number...

My implementation went like this:

Set objSysInfo  = CreateObject("ADSystemInfo")
Set objUser     = GetObject("LDAP://" & objSysInfo.UserName)
Set objComputer = GetObject("LDAP://" & objSysInfo.ComputerName) 

If objComputer.operatingSystem = "Windows*Server*" Then
    Quit
Else
    strMessage = objUser.CN & " logged on to " & objComputer.CN & " " & Day(Date) & "/" & Month(Date) & "/" & Year(Date) & " " & Time & "." 

    objComputer.Description = strMessage
    objComputer.SetInfo 
End If

Call the above script from a GPO, using: User Config -> Windows Settings -> Scripts -> Logon

Then just update the permissions on the OU, so that users can modify the computer object descriptions, like this:
