Finally all orders have arrived. Raspberrys and Heatsinks had to be sourced different than the Ubiquiti switch and mircoSD cards. Luckily someone just started distribution of Waveshare PoE HATs here in Germany. So those did not need to ship around the whole globe.
So it is pretty satisfying job to prepare and assamble the cluster hardware. Heatsinks had to be sticked on the Raspberry and the standoffs needed to be attached to the PoE HATs. Then the Raspberry and PoE HAT could be bolted together.
Since microSD Cards tend to fail after certain period of time, i opted for endurance versions of this well known brand. These cards have been developed especially for long operations in surveilance cards and i think they are also suitable for a Raspberry Pi4 which has to run 24/7.
So I still need a case for all the Raspberries. Not easy to make a decision for that „case“ topic …
