I almost went the same way, but thoses Lian Li and Coolmaster cases cost a fortune. I have the same type of optional front USB motherboard. Put what I did, and I think is bettet, is I bought one of those usb motherboard to input adapters. They fit in a pci slot in the back of your case. You can get them anywhere. CompUSA, BBuy, Fry's. I have an Antec sx380 case, they make a 5.25 usb adapter that you can put in your "extra" slot facing the front of your case. I went with the rear adapter, 12.99 and bought a usb keyboard with two usb ports on the side. One for the mouse and one for my gamepad. Plus I don't have wires coming out of the front of my case. I've seen them, they are ugly and in the way.🙂
But that is just my opinion, and as I have leardned from being engaged, my opinion is meaninghless!? 🙁
LOL 🙂
