Two 4 port network cards?

Yeah but on a single card apparently. He got those as a sample for the build but they don't space properly in an ATX case.
He asked if I might be able to locate one that would fit in a PC. But I really have no clue, all I've been able to find are those like that which fit in switch box designs.

I think it would be too big, no? RJ21 will give higher port density.

Ah yeah no, not all 8 on a single slot, but dual slot with 4 each like the photo. But the issue is the spacing between the sets of 4 and the next set isn't large enough so the second row is falling behind the ATX cases cover and you can't plug anything in to them.
I'm not finding anything with a larger spacing 🙁 they might not manufacture them after all. The current solution is a cable with 8 ends, but he would rather have one of those jacks with the 8ports instead.

As you noted, the 8 port modules are off the shelf items for on networking equipment. They won't have additional spacing for fitting what you've described. I've never heard of an 8 port PC NIC. Certainly, 8 port cards for chassis switches are common, but they're all inline and will be too large to fit a back plate.

I think your best options are likely going RJ21 or installing a second 4 port module via a riser.

Why not attach it elsewhere to the case (or in its own small case), and link it to the card with a cable?

He says it's for an 8-port specialty NIC card some client of his wants designed, but only if it's possible to.

In that case, make the card single or dual slot with one or two connectors, and the 8-port jack plugs into those connectors via an adapter board on the outside (basically sandwiching the slot backplane between the card and the 8-port jack). That should work with most computer cases in the space that needs to be left free behind a computer.

Actually that seems to be their old solution already. They want to get rid of the current 8-port octopus cable and have a more elegant solution.
Since I cannot locate a jack block with the correct spacing I'll assume they simply don't make them. They aren't exactly in high demand 😉
Thanks for the help
