You can run a pruned node that requires less storage, that's one option. If possible in your region, you could buy a used business class laptop
[1], which are not expensive, you don't need the newest shit gear to run a node. Run some Linux on it and again a pruned node or upgrade the SSD to a 1TB model for an unpruned node, those aren't terribly expensive, even 2TB models are quite affordable (ok, it depends heavily on your overall income and I'm aware that not all parts of this world are equal; I'm speaking from a 1
st world perspective).
You can run a node with a Raspberry Pi 4B or 5 (4GB RAM will do fine, 8GB RAM is preferable), no need for a Laptop and a copy of Windows. I have three nodes on such Raspi 4B devices, low power consumption and perfectly fine for a node.
[1] Usually those have easily accessible and replaceable memory and storage devices. I'm not speaking of Apple and other crap that's not build for easy repair and upgrade. Don't give your money to such companies!
