@olivierlambert sure. it's very long though, I grepped out the intel devices for a shorter version on the forum, and attached txt files with the full output.

I forgot there is also a gt 8800 present but i don't have the internal power cables for it (yet) and it looks like it needs them to even show up (some will work just die when they need more power). ill take it out next time I open it up.

the riser layout physically is this (from the back):
10gbe_8800_1050
6400__8400
6400
