If I wanted to run on a PC, how much does that PC need to be up and running?
For a bitcoin node you could leave it running for a few hours or days at the start to download the blockchain. After that you can shut it down as desired and every time you reopen it bitcoin core will download the blocks you missed which shouldn't take long as long as you open the computer every few days. Lightning nodes need to be online as much as possible.

It seems like it would take up a ton of space does it not?

The blockchain is 693 GB right now but you can run a pruned node if space is a limited. A pruned node still downloads and verifies all blocks but deletes them past one that increase beyond a certain threshold that you can set base on your needs. All newer computers have more than enough space to run a pruned node.

How small can a pruned node be?

Last I remember you can prune the blockchain down to 550 mb, but you still have to store the utxo set which is maybe 10 to 15 GB. Looking at your other comment a 256 GB ssd would be plenty.

Oh wow. that isn't big at all. Good to know. If I have issues with my pi, I might try that out.
I think right now it is less than 700 GB. Depends on what is a lot for you. Storage is quite cheap now. Unless you mean physical space.

I mean my laptop doesn’t have 700 GB of storage 😂

@ChrisS says you can prune it down to under 20gb or so.

My Mac only has 256 gb. They charge so much for storage so.i went with a smaller size. Kind of annoying..

Good to know. I am off-grid so sometimes the power goes down and I can't run a PC 24/7.
