I'm fairly good with a soldering iron, but there's several SMD parts there, that would probably test me a bit. If this was really to appeal to low-end hobbyists, it'd all be through-hole parts.

High end hobbyists are already building their own single board computers based on their own designs.

Is there a way to browse available projects on your site? I'm interested in taking a look around, I love to build weird things :)

That's very helpful, thank you!
