    I'd like to add a 10Gb NIC to my main desktop. The motherboard is an EVGA z370 micro in a micro ATX chassis (4 I/O exp slots). My GPU takes more than 2 slots and obstructs the second x16 slot. but I do have a 3.0 x4 slot in the bottom slot. x4 should be enough to run a single 10Gb link (I only need 1), even at PCIe 2.0.

    I've been searching but can't seem to find any 10Gb SFP+ NICs with a x4 interface. all seem to be x8. I found an ASUS x4 NIC, but it's 10G-baseT, not SFP+.

    I do NOT want to modify the slot by cutting the end open.

    Mellanox CX311A-XCAT should be good enough

    While I believe that by far the better option is what Pradawny suggested, another option could possibly be to use a pcie riser ribbon cable with a low profile card (might be usable from the slot that is obstructed by the GPU).

    I believe single port 10Gb nic is x4. Look at Intel cards.

    Hi. check LR-Link, 2 port that can support rj45 sfp. A full pci-e 3 running on 4x. You can run 2 port nearly at 10g at same time. Work with mikrotik router and the 10gb hub too.

    You could cut the card instead of the slot. As long as it is a clean cut to the exact pin where x4 ends it will be fine. You technically only need to make a notch for the slot, but its easier to shear all the excess off, especially if a board has components sticking up there like jumpers or chips.

    There are a ton of dirt cheap 10G SFP cards on ebay so you could buy extras if you mess up. Like $10 for a mellanox CX2 or whatever.

    Startech have a model based on the Tehuti TN4010 chipset that comes in PCI-E 4x - PCI Express 10G SFP+ Network Adapter Card | Network Adapter Cards | StarTech.com

    There aren't loads of them floating round dirt cheap on ebay but they are lower power consumption than the old models (don't even need a heatsink) and we've been using them in production on servers at work for a few years now without issue.
