I split my loads (gigity) between the power hungry NAS and a passively cooled low power Proxmox host.
For me, most 24/7 activities are low CPU - like Home Assistant, so it needs to be there, but it doesn’t need to do anything.
Other VMs are ansible, uptime kuma, smokeping, etc… the most they use is RAM
Then the (relatively) more power hungry NAS powers up 3 times a day to syncthing everything, maybe upload a backup, and if no-one’s using Immich, etc. then it’ll power back off again.
The only other thing I have yet to downsize is my pfSense box (still a low powered device, but has fans…) and a Raspberry Pi I use for my Zigbee network.






And, even further: a rust implementation vulnerability too?
(Waits for C vs Rust war to start…)
