hey guys, i was looking at the dimension e310. Very respectful machine for a media center pc might i add. i was looking at the back, and what happened to the mouse and keyboard port?!? Do you mean that if you purchase it, you have to use the USB ports? my friend is thinking about getting one, and like me, he has the microsoft wireless optical desktop elite. the wireless plugs into the keyboard port, and the mouse can be put in the a usb port, but comes with an adapter so it can go in the mouse port. my friend needs all of his usb ports, since he is currently using 10 of them on his current dell.
