Thanks guys. Going to go with black rims/hubs. Hopefully the silver spokes tie it all together alright. I'd love to get black rims with silver spokes and silver hubs, I don't think I'm going to find a reasonably priced prebuilt set though.

@Scrod re:dropouts, I won't be running it like that, I just wanted to see it for visual reference and couldn't stand the idea of a saggy chain. I'll be running an 18T or 19T cog on the final setup so it'll be further forward and I'll shorten the chain if necessary.
