the Supermicro's are not bad boards... i dont know about any dual xeon cpu boards.. but about the USB 2.0 i have an Intel 850EMV2 board.... which has four usb ports in the back and two frontpanel usb ports... yes some motherboards have built in usb 2 controllers. like my NEC USB 2 controller which is built in on my motherboard.... you only have to install the drivers(can with my mthbrd cd)... and just make sure you have USB 2 compatible devices
