OK, I bought a Corsair Obsidian 650D which comes with 2 USB 3.0 front connector; however, these USB 3.0 connectors in the case only provide a USB pass-through cable. I have seen several USB 3.0 to 20 pin adapters, but I want to get people's opinions. I really want to buy the best solution for this problem. I can't believe that after paying $140 for this case, I get such type of connections instead of the proper 20 pin USB 3.0 connector to the motherboard. In advance, thanks for everyone's help here.
