My post was mainly answering to the OP comment and your follow-up. > It still makes sense to use a decade-old computer. >> I don't really think it does, at least not some of them. I totally agree with you regarding the homelab topic (although personally, I started using low-powered refurbished x64 thin-clients (using about 10W) in place of a RPI cluster, mainly to get real sata ports on them.) My point is that, environmentally, continuing to use a 10y computer rather than buying a new one is generally a sound advice (assuming it does still what you want it to do). Since I didn't have data for a 10y old computer, I used what I could find: the 2016 vs the 2021 Macbooks Lifecycle assessments from Apple. The same point would probably stand between a 2010 computer and a 2023 computer. Even if the old one is less energy efficient, the 150 to 300kg+ of CO2 you save not building a new device goes a long way. And instead of consumer devices or RPi, if you are talking about datacenter-class servers, then you save even more CO2 by prolonging your device life since a new server's manufacturing footprint is more like 1500 - 3000 kg CO2eq.
