I think I'd rather have an AT-AT with a gamecube in than a nicotine yellow millenium falcon. XBoxes are really easy to mod though, they're basically contained within the plastic box so they can literally go anywhere that they can fit comfortably, it's the size that put's a dampner on things though, that falcon is massive and certainly not worth £800.
A sandcrawler would be a cool model I think, like with an XBox inside plus plenty storage - it could be used like a coffee table.
