There are no Raspberry Pi's or SD Cards in this build at all. The one issue Bert had was totally my fault, as I mislabeled an emmc storage unit and installed the wrong one because of it.
The nice thing about the hack0 built is that there is no SD cards involved. I agree it’s one of the weaknesses of the raspi. Also depending on the node software you run, and you use a fan it can be really noisy. If you use passive cooling on the pi that was not put there properly it can overheat. We’ve seen quite some pi failures with different causes. A hack0 is a totally different kind of build which I think many would appreciate.
It has lots of potential indeed, but I'm obviously biased. Another pro of passive cooling is that there are no moving parts or bearing which all break eventually after a certain amount of time. The weakest link is the NVME, which should be replaced after five to six years.
