If I were to get the one on ebuyer with the quickcode 411061 (I'm having to do this through the xbox, you have no idea how much of a pain in the arse it is!) could I legally put the hard drive in there from the old one and run everything as it was but with a big hardware upgrade? I'd use the 1TB drive in a caddy, or is that a shite way of going about things? Don't thinl I can put this Windows 7 on it anyway as it's an OEM version.
