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.
