This is the upper shield of my case for Raspberry Pi computer (see www.shapeways.com/model/486999/raspberry-pi-case-1-0.html).
It is intended mainly for replacement in case of damage.
You can also order it with the related bottom part (http://www.shapeways.com/model/720306) if you just want a 2 colour case.
Led lightguides are not included in this model, they are available here: http://shpws.me/6yFP
If you need an enclosure for your Raspberry Pi computer board, you should choose the whole case.
