Thanks all for you advice. I think I'll be getting the unit Big Red suggests, as I already have an I.D.E. 500 gb Seagate to go into it.
Good to hear that swapping is easy too. I shudder when I think of having to change out my Vantechs
Too bad I have the drive already, as I do have eSata support on my Asus P5B motherboard too. Oh well....
