I have only two device, 1 laptop of 8GB Ram, 256GB Rom, Intel Core 15, 7th Gen, i consider this device an average of what any user not deep on tech should use. Ideally not suitable for hefty crafts. Then i also have my Android, same 8GB and 256GB storage, still what an average would use.
Your PC will runs node seamlessly as long as you don't over load the drive.
Yes, even 2GB Ram PC can run a node. My node configuration (pruning) is set to 2000MB which is 2GB of drive space. While i have to prune there are PC capable of running full node without upgrading the drive or having external SSD.
For those running multiple nodes like Bitcoin full node and LND should have a system with higher processor and Ram, this makes up how fast and conveniently the PC can run both.
