See my system specs, currently only have USB 2.0, and don't plan to do a major MB/CPU/GPU upgrade till later in the winter. So, for the time being, I'm looking for a USB 3.0 add on card, PCIe. It'd be nice to have some front panel connectors, but I'm not stuck on that... I have a few 5.25" drive bays free. My HAF case was made before USB 3.0 came out. Any advice on a good USB 3.0 card and/or what to look for? When I do upgrade, the card will stay with the old PC, and will still be used.
