I have a Dell Optiplex GX 280 built 2007...rebuilt 2011. works great. I need to know which back USB port is high speed and how you can tell. I use a broadband external modem for internet connection. My brother says I need to find the high speed USB. Thanks so much. Laura Lilovich

depending upon your re-build... you will at a minimum have usb2.0 hubs and possibly usb3.0, usb3.0 can be identified by a blue bar in the usb. usb 3.0 is fastest.
