These look better than standard metal green motherboards.
They are from a high end network storage array.

I almost just sent them in as metal socket green motherboard but figured I would ask here first.

The one without the CPU socket I was figuring was Low Telco at least.

I guess I will send in the ones with the CPU socket as metal socket mobo
and the others as low telco

You could email Chris at Boardsort and include a link to this post.

From the video made by Chris:
Low telecom is high telecom plus junk. From what I can see, the boards that you posted have very little junk. Probably closer to the high end of periph high grade. Look at the video on high telecom and the one on periph high grade, then decide what your boards look most like. I even look at the boards in the background in the bin that he is pulling from. They will regrade, without malice if you make an honest mistake.
The metal socket mobo is just that.
