Laptop , i3 8th generation, 12Go RAM, 1To HDD. Why ? Because that old laptop was not used since a long time ago 😅

I have an old laptop too. But it shuts off after 15 minutes while its plugged in, and does not even start without being plugged in. 😂 Maybe not the best.
But maybe, I could just try to repair, and utilize as btc node. That kind of make sense.
I have also an rpi, but too much people says it is shitty for a node, so maybe there could be some truth to it.
It all depends on how much time and money you are willing to put for this 😁
I like to do it cheaply, but in a way that it is cheap for long term. So I don't have to replace it soon.
Raspberry Pi performing well for me.
I picked that platform and https://raspibolt.org/ because (a) it’s a lot of fun for a hobbyist and (b) working at the nuts and bolts level helps build understanding of the ecosystem.
