Lots here.

I don't think there's much product differentiation on USB 2.0 PCI cards. I'd just pick a price and get the best brand name you can from there. How wrong can you go for $30? I assume you're keeping your current MOBO with the new case. Usually the case USB connection wires are terminated with .100" pin headers for connecting directly to a MOBO. You might need to do some wire hacking/replacing. There are also bay hubs that do the same thing, something to consider.
