Oh and as for the VPS, I did do that once and ran out of disk which is why I went to the home node idea where all I have to do is add disk to the laptop.
Yes, you need sufficient disk space. It's not too expensive these days. But of course, it's cheaper to use disk space you already have at home.
Also, your home-ip will be registered many places as a bitcoin-node ip, you might like that, or you might not like that. Some people do not like that, so they use a VPS instead.
