No Rurouni NO! If you have seen the inside of the Xbox, then you would know that it's big for no good damn reason. The Playstation 2 in it's current form could fit a hard drive inside, and it still wouldn't be any larger than it is now. Xbox is simply that, a big ass box. Having a hard drive doesn't have a damn thing to do with it. Many computers are smaller than the Xbox, which further proves my point. And they have hard drives, along with many other things.
