Would be better with all the screws...
Although people have the tendency to complain about the cheapness of this acrylic case, I think it looks quite nice for the price and has the advantage to let the Wi-Fi signal in and out nicely. Why 3 stars then? Glad you asked. Simply because none of the ALLO DIGIONE SIGNATURE parts (case or boards) comes with the small spacers you need to secure the pi board to the base of the case. I am not the only one to complain about it and yet, still happens. The other star is for cheaping out of providing assembly instructions for the signature version of the the Allo digione board although it is the one that drains the most money out of your wallet... Despite all of this, ALLO support was really effective and I managed to get my 4 little screws before I could even say "quidditch"! The quality of the equipment, I have no doubt that it is decent, but right now my amplifier is a modest Onkyo TX-NR646 and the combo with my B&W 703 S2 is absolutely terrible and I can't wait for my Atoll IN300 to be here...
Bottom line, good product, good support but bad logistics.

Simple easy to assemble case
A simple cheap acrylic case for the DigiOne Signature kit and RPI 4. If there were an aluminum/metal case I would have bought that instead.
