 The *indent* checkbox enables indents for a select group of components defined in SBC Model Framework.  The currently support components are - video-hmdi_a, video-hdmi_micro, video-hdmi_mini, power-pwr5.5_7.5x11.5, power-pwr2.5_5x7.5, usb2-micro, usbc-single_horizontal, audio-jack_3.5. The *accessory name* pickbox uses the unique accessory group name to associate a given accessory set with a case design.  Entries are stored in the file sbc_case_builder_accessories.cfg which is covered in detail with the Accessory Subsystem in this document.  The remaining two entries select the color and proportional font used with the *sbc information* display when enabled in the *View* tab.
 
+#### NAS HD Options
+The *nas sbc location* pickbox allows the positioning of the SBC at the top or bottom of a NAS case.  *hd bays* sets the number of drive bays, *hd reverse* checkbox rotates the drives 180 degrees while *hd center* centers the drives in the x-axis.  The next entry, *hd space* determines the spacing between drives and *hd y position* and *hd z position* sets the respective axis locations.
+
+#### Accessory Group Name 
+The *accessory name* allows the selection of an accessory group to be associated with the current case.  These groups are located in the file sbc_case_builder_accessories.cfg and provide a means to add or subtract geometry, models and add items to the print platter.  See the *Accessory Subsystem* area below for further details and use.
 
 ### Standoff Tabs
 There are 3 types of standoffs available in the user interface, SBC Standoffs, Extended Case Standoffs and Multi-PCB Standoffs.  The SBC standoffs control adjustments for the SBC or pcbid 0 as defined by the entry in SBC Model Framework file ./SBC_Model_Framework/sbc_models.cfg.  The Extended Case Standoffs control case corner standoffs when the case exceeds the SBC size by the *SBC Standoff Support Size*.  The Multi-PCB standoffs are used for additional PCB in multi-PCB configurations as defined in ./SBC_Model_Framework/sbc_models.cfg e.g. pcbid 1, pcbid 2, etc.  All three standoff types have similar controls made up of a global tab and individual Settings tab in the GUI.
