alt Hacker NewsI was happy to see that x64 mini computers have really come along. Some of the units from China are really impressive with some exposed full PCI-E buses.
Arm64 is still limited for sure, but with Snapdragon and Windows finally committing to ARM I think the future is bright for that. Just not here yet.
A thunderbolt 3 connector is 4 PCIe lanes, isn't it? I know there can be compatibility gaps, but there are definitely TB-connected enclosure boxes available. NVMe connectors are also 4 PCIe lanes, and I believe any of those can be broken out and used for whatever (m.2 cellular data modems for example).
Are you thinking of plugging in actual consumer expansion cards, or are you wanting the lanes broken out on some kind of riser where they can go to hardwired stuff on a carrier board?
