Came across some large router's cisco 2900 series was one of them.
I normally get pc's and the like.

I feel you should email Chris at Boardsort about the server boards. Also. Front and back pictures of those smaller boards can be a help. I posted since I noticed your not getting a timely response.
Here to learn like everybody else.

The group 1-5, at least high peripheral. 3 maybe hits low telco.

2-3 seem like they're low telco to me, 2 having a CPU socket is weird (for me at least).

1 is interesting (mainly cause I keep looking at the capacitors and seeing eyes with the black dots as pupils and faces :D) low telco seems likely

For what it's worth, if I'm replying to a bunch of stuff around a post but not it, I tend to be more unsure about the grade.
