The case is self-assembly: there are 6 plates to be assembled around the Raspberry PI with a diagram. Not too complicated, you just do not get the wrong direction. The set fits perfectly, the Raspberry PI is properly seated, you can open / close the cover and remove the same everything. Good surprise: there are 3 small radiators to stick with double-sided already fixed on the radiators. However, the temperature gain is minimal: about 1 ° C, maximum 2 ° C as they are passive and modest in size.
I removed one star because the plastic is not so transparent and that there is a bluish part. So it's less class than the pictures.
