Your DAC instances are out. Its 5 meters for 100 gigabit Ethernet DAC and 3 meters for 200 gigabit Ethernet. So even allowing for running on the motherboard you should have a foot or 2 off the motherboard to play with.
Not all thunderbolt cables are electrical.
Some are AOC and AOC Thunderbolt 60meters ~ 200feet.

AOC thunderbolt cables have zero performance loss out to 60meters. At 60 meters you start running into a power provide problem. Do note AOC is optical inside even that it what looks like normal copper plugs both end. You get AOC these for long run USB, Thunderbold, server to server in rack direct motherboards connect... There is no repeaters in these cables the covert to optical is at both ends. Yes AOC USB cables have been used in some of the China PCIe 3.0 break out cables that give you 25 feet/7 meters. This why I wonder if the person cannot tell the difference between an AOC cable and a DAC cable. DAC cables have lots of interference problems. AOC are a lot longer and very light on the interference problems there are some forms of PCIe 3.0 breakout cables that are in fact AOC. I would expect to see AOC cables appear for PCIe 4.0 to 6.0 as well. 60 meter runs in AOC cables is not that odd.
I do wonder how they are going todo PCIe 7.0 hopefully not AOC run around the motherboard because that would be expensive pain in the ass to make.
