I would prefer a black background also; massive amounts of white space coming from a monitor is hard on my eyes, and make me more likely to leave the website quickly. I vehemently dislike the rusty brown (or whatever color you want to call it) border. Selecting another color out of the logo (since this is what seemed to happen here) and toning that color down abit, if needed, would really look better. Also would have the added benefit of making the logo stand out more.
