I also voted sister site, but it may be better for business reason to just integrate it as another heading under the Beyond3D.com domain (read: more views = more ad dollars). It should be a relatively simple task of dividing the front page to accomodate both the main, original thrust of this site, and these new, related doo-dads. You might have to expand the main page to assume a 1024x768 screen res to comfortably fit the new content, though.
You'll want to provide a distinct forum for that, though, or specify a current forum (Hardware Gab) for it.
