I don't know how it works for the slim consoles, but for the phat ones you would need a certain type of Western Digital drive, a disk image of your desired size 360 HDD (60gb, 120gb, 250gb) and some software to apply the hack. If you bought a 640gb drive, you'd still only get the size of the 360 HDD image you were using.
I doubt MS will have made it easier to use a non-MS HDD on the slims so I'd expect that's the minimum you'd need to do.
