I have long been looking for a case for my Raspi. From the quality of Taritec I'm surprised. All parts are absolutely Precisely shaped. The circuit board of the Raspi is screwed to the housing. Since absolutely nothing wobbles. The cut-outs for all connections with millimeter precision. It needs to be pressed or canted nothing.
Actually you do not need the video for the assembly. Damage may not. After the Raspi is screwed into the housing within 5 minutes.
