I'm not sure I understand the bottom piece but otherwise I like the concept and should be fairly easy to figure everything out with time 
Glad you like it too, Xondat. How about making that the X40?

What I meant is that the bottom piece is a flat plate screwed into the case from below. Similar to the old Mac mini, the case seems unibody because the bottom is hidden from sight.

Like the Daisy, the order from top to bottom: one-body case, plate, PCB, acrylic bottom piece, and screws.
