External HD that matches Retina Macbook

I think the best looking external HD that would match is the "Seagate Seven" available on Amazon

It looks as slim as the new MacBook and although its only 500GB I think it can do the job.

There is a gold HGST Touro

I have a WD Air, and for all intents and purposes, it's the closest I've got to getting a Mac look for a hard drive.
