i have an old CPU case that has two traditional front USB 2.0 ports. my new h110 motherboard supports one USB 3.0 header (can be connected to two ports) so i was wondering if i could use the same old case without sacrificing the advantage of loosing easily accessible front USB 3.0 connectivity. i know the cable that connects the port to the header is different but is there any other way i can get front USB 3.0 connectivity though my case supports only USB 2.0?
