You're confusing nodes with mining, you don't really need much more than a RasPi with a sufficiently large SSD to run a node.

Even if so, I still don't see the point of wasting the space and power, however small, on what has no use being in space.

And bandwidth.

You are confusing BTC and ETH... A fully validating BTC node can be run on a raspberry pi, a full ETH node requires much more equipment.

To run a node you need low spec PC so the power consumption is probably around 60W.

Most nodes don't mine.
