Following a lightning strike my dell optiplex 9010 sff now has a dead lan socket. Can someone recommend a pcie win10 card that I can install. Tried one which didnt even showup in device manager. I did disable on-board lan in bios.
Yes, the PCI-Ex4 expansion slot will accept both PCI-Ex4 and PCI-Ex1 cards.
Just look for cards that have low-profile brackets. Those will fit within your SFF case.
