I've been looking around looking to build my next unraid build. The next build is going to be a little more power conscious, as I will be moving to a place with solar. Ideally less than 100watts under idle. Currently looking at getting an intel 12600k and a used Asus Prime B760M-A AX. Any other comparable or better MBs? Or other power saving tips?

My Unraid build mk2:

Darkrock classico - you can roast me for the case choice here. But since its cheap and just an Unraid media server and wont be seen much, I routed some of the cabling underneath next to the PSU and along the inside. This way I can still close the back panel.

64GB ddr4 ram MSI Rtx 3080/ EGVA rtx 3060 - I 3080 for now because it can still transcode but will cause system to reboot if used with display
