I'm pretty sure you won't get DQ'd for going over $10k. At least, I'm assuming the OP was more interested in your dream bike than your ability to stay within (a fairly generous) budget.
Lonesomesteve probably DNF's though, because however spokealiciously fabulous his ride, I somehow doubt that he'd actually ride it far enough in one go to call it an "endurance" bike. Me, I'd just get distracted by my reflection in the top tube!
