So far, I'm satisfied how my RPi4 is running the node. I had it on for a week or so. The computer was much more expensive than it should be, but it was either that or waiting until October. I didn't realise there were cheaper options (like the Intel something, mentioned in one of the comments). I also don't have space to keep a whole PC running a node. I was considering running a node on my laptop, but that would either consume a tonne of energy or the node would be offline most of the time.
