Yea this was their best deal in a long time but I ended up cancelling.
Reason being I want to use a WD Scorpio Black and buy an enclosure for it. I have the 360 Slim version so I would of ended up having to crack the case open on that drive and voiding the warranty anyway.
Doing it this way buying my own drive, I have full warranty on the hard drive.
Price wouldn't be much different, just have to flash your own firmware is all and buy your own enclosure.
