XPS 8700 Mother board question Re/MSATA slot

Do all configurations of xps 8700 systems have motherboards with a slot for a xsata card? I have an system that I purchased from Dell outlet and want to have the msata board available when the system arrives so I can install the OS on the xsata drive instead of on the Sata hard drive.I can't tell from the cart detail listing on my confirmation.

Thanks
