I'm more of a software guy, but I've been looking at the Up Board lately. I was thinking of building a pocket laptop using a Nintendo DS case. One thought I had was it would be neat to extend it's capabilities with an external graphics card. I noticed it has a PCI-e Gen 2 bus, but it seems to be taken by the Ethernet port. Would it be possible to de-solder the ethernet adapter, and re-purpose it for externally connecting a PCI-e graphics card?
