I have 3 internal HD's for my G5, only two of which are actually in the G5. The 3rd I have in an external case. So, I'm selling the G5 and I'm wondering if I can easily sell the 400GB internal drive. I bought it new for $140 less than a year ago. Is there a market for used internal drives? What would it be worth? Or should I just give it to the buyer of the G5?
