Ooh hey, I actually got a 300GB Seagate drive for X-Mas too 🙂 You've probably already got a case selected and on its way and everything, but just incase you don't, I'd recommend checking out Mad Dog Multimedia's cases. I got one for mine, and it works great. Both USB/FW, externally powered, with cool flashy lights and it was only $45 at circuit city!
