I had an older rpi model without wifi where the network adapter got broken.

Other than that, I've been running 3 rpi at home for home automation they have been working with no issue. But it turns out that they are a bit underpowered to be used as a minetest server.

I never had a corrupted sd card on those. But I had an android nokia phone that corrupted like 3 sd cards before i gave up and stopped putting new ones.
