Optional (DNF) Mouser parts
These parts are not required for a normal build - in general: don't buy them! They would go to the greyed-out locations specified as DNF ("do not fit") in the BOM above. If you want them anyways, e.g. for a special usecase, you can also copy & paste them into your mouser cart:

Frontpanel Scheme
If you consider designing and building your own case, we've released the acrylic case frontpanel scheme for you.
Note the raster of 3mm is marked in the drawing and is used for all small quadratic case "interlocking" cutouts - this measurement can be used as a scaling reference, e.g. if you want to print an own design using a 3d printer.
