If you are just now getting a 360, it will most likely have a Hitachi v0078FK or a Samsung MS28. A Hitachi v0078FK should flash just fine with your current setup. You would need to purchase a VIA PCI Sata card if you get a Samsung MS28. There is an extremely rare chance you get the new BenQ VAD6038 drive, appearing in recent systems. There are only 4 people over at Xbox-Scene who have seen this drive. If you get this drive, it would not be flashable at the moment (it's like brand new, you probably won't get it).
