If you add lightning and core. it is a matter of time before the pi can't keep up. Pick up a n100 intel mini pc low power and easy to spec out zero problems.

Ya looking at nucs but decided not to for now. I have another pc just sitting around most of the time and figure I’ll use that for the time being
I have an old laptop I would like to make a node. Any idea where to find a guide on how to do this?
A node runs 24/7/365 so laptops aren't the best for that. A cheap used dell optiplex 9020 8G 2TB SSD will be great node box. Start9 DIY is a great place to start.
All of this.... just do this
DIY option is https://raspibolt.org/
Just make sure to download x86 versions instead of arm.
