Rolling releases for issues with newer hardware and the AUR. That’s really all there is to it. There are plenty of ways to be “unique”, but at the the of the day, nobody else is ever really going to care.

If I bought myself a 6 year old Thinkpad, I’d put Mint over Arch on it in a heartbeat. For the desktop that’s constantly upgrading, it gets Arch because it has the fastest releases and biggest community to troubleshoot stuff.

You can always just undervolt the cpu and take out the gpu. Sure, a 1000w power supply is going to be inefficient at 20% draw, but if you already have old hardware it isn’t always cost effective to replace it just because of a higher power draw.

Also the pi is great for stuff like dns and network storage, but it’s going to struggle with transcoding as a media server. I can’t speak for the 5 from personal experience, but the 4 was completely incapable as a jellyfin/plex server. I just use an old stripped down computer for media and the pi is relegated to dns adblocking.
