With the system you propose you should be fine.<br>
I would recommend upgrading the "40GB 320 SATA-II", especially if using Windows 7 which I recommend (Windows 8 is a complete new interface). The size of the drive tends to shrink every time windows updates the system!<br>
Good luck.</p>

I'm afraid that scanning film on any flatbed scanner as suggested, is going to disappoint you in the long run. You only find this after many hours of work. But than again, it all depends on your expectations. Good luck.</p>
