I'm planning on using the exact current harddrive with all existing software for the new equipment. I've changed out stuff while using same HDs several times before, my only need will be the driver to the new graphics card. that should negate my need of a new driver. And also I'm pretty sure that the things been running on a windows update driver for a few years anyway from when I wiped the machine to put Win7 on.
but so each of those is actually 2 USB ports. Well thats good then, thanks for your help.
