SilverStone 4-Port ECU01 PCIe Expansion Card Video Review
 

"The SilverStone ECU01 is a 4-Port PCIe USB 3.0 PCI Expansion Card with attitude! With two 19pin USB 3.0 connectors, this product is capable of 10Gbps. It also supports the USB Attached SCSI Protocol and Turbo Boost. It's perfect for adding additional USB 3.0 ports to a system that doesn't have any, or for that matter one that does." ~3dGameMan.com
