Thank you Garfield Modular,
It is great to have such a warm welcome after Lurking around here for ages. Without building the kit I already spotted the big hole: I havent planed for a nice filter.
But I will take your advice by heart and first get up and running with the most basic setup, so I can judge the further build better.
yours
