My Silverstone Raven RV-03 case has two front USB3.0 ports. But there is a catch. Instead of having connectors that would plug into one of the motherboard headers, it has the regular USB male jack. So for you to get them to work, you have to plug them to USB ports on the back of the motherboard. What actually happens is you simply move two ports from the back of the motherboard to the front I/O. Usually they would plug to a motherboard header without wasting your back panel USB ports.
