Peter; I don't have a clue what the OP's mechanicals around the pci slot are, but I had a heck of a time with the machine on TLM, the backplane and the mobo didn't quite geehaw, and it lifted the rear of the 5i25 from the slot, repeatedly. Backplane was miss-stamped, and I couldn't bend it back toward the mobo and keep it there when the cover was screwed back on. One of the reasons I threw money at it and now an OAK shoebox with a D525MW mobo is on that shelf, zero problems since. > > 05/29/2017 10:15 AM, Marius Alksnys ra: > >> Peter, can you repair or help me to repair this 7i77 board?
