> There's at least a little flexibility with the graphics card if you move the board into a different case—there's a single PCIe x4 slot on the board that you could put an external GPU into, though many PCIe x16 graphics cards will be bandwidth starved.

For LLM inference, I don't think the PCIe bandwidth matters much and a GPU could improve greatly the prompt processing speed.
You can also use an adapter to repurpose an M.2 slot as PCIe x16, but the bandwidth is the same x4
There are no situations where this matters yet. You have to drop down to an 8x slot on PCIe 3.0 to even begin to see any meaningful impact on benchmarks (synthetic or otherwise)
