Something with coreboot will be much more power efficient
Wanted to upgrade one of my NAS devices for some time. One of my computers i use for this is overkill: a gaming computer with 32GB, modern GPU, and sucks up a lot of power.
Had my eye on the LincPlus N1, and especially since Unraid is the base OS.
Come to find out you can "kickstarter" back the LincPlus N2 for cheaper than you can buy the N2 today. Not bad! Should deliver in April

Just don’t want it draining watts all day
Dasharo version is good, but starlabs has the best power efficiency coreboot version.
