Not that I'm aware of. I'll typically start with Ubuntu Server and add a DE to it, but this time I did a clean Kubuntu install. I'm looking at my resource monitor right now and it's been sitting around 200 all day for Plasma. Perhaps if you add up all the rest of the KDE background services like KDE Connect, klauncher, etc, you'll have a grand total above 300. But I have the hardware, so I don't mind.
