Use the 4 long brass hex posts on the top acrylic cover and secured them with 4 x short silver Phillip screws as shown in the picture.
This is what it should look like.
Build the outer frame around the Banana Pi computer Board as shown in this illustration.
IF ONE OR MORE OF THE PIECES DO NOT FIT TOGETHER READ ON: Please Do not force the pieces, this case fits perfectly but if it doesn’t it is because the piece you are trying to fit is either upside down or backwards, simple turn the piece around and try again DO NOT force it or dremmel it.

Secure the banana Pi Board with the 4 x short brass hex posts screws.
