Get yourself some old cisco 3600 re-flash it with standalone firmware and get enterprise class WAP for cheap.

yes, is what i get reading about that server backplane. NVME part will need another “controller”

what is wrong with old good LSA 2008 based HBAs with SAS-to-Oculink cable? and for NVMe part, adapter is just port format converter, pick any.

ICINGA/NAGIOS? you can even feed data already collected by Prometheus to it if you want.

Ahh age of switching PSUs and led lights. 20 years ago you will notice it in an instant.

A4-6210 with build in GPU has TDP of 15W. There is no point to optimize anything it is seeping power already. may be try to use tlp to limit max charge level of the battery ( i’m not sure is you laptop is supported). You can play with governors too, but I personaly will not bother. You obviously need multiuser.target but not GUI.

It would be useful to know laptop spec. In general, do not bother power consumption should be lower enough as it is.

Symphonium is another good mobile client.
