I bought one a while back and played with it before installing a 2TB NVME and turning it into a node thatβs much more performant than the Raspberry PI 4 that it replaced. At the time buying a new PI would have cost me more than the Nuc did. I think PI prices are down a bit since then, but the performance of a Nuc relative to a PI is worth any premium IMO.
Note: I wouldnβt have converted it to a node and put it online if I had ever exposed my real private keys to that machine. I only used it to play with toy keys and to test various options for manual keygen etc. Trusting real private keys to general purpose computers is risky enough. Doing that and then connecting that device to the internet later is way more risk than Iβm comfortable with.
