Extra grafix card
USB extendor x2
it would be a bit of a bother havin to go upstars to turn ur PC on but if u want a wireless keyboard makesure it reaches that distance.
connect your monitor to your extra grafix card
plug usb extender/(wireless keyboard 'n'mouse)and connect keyboard and mouse.but i wouldnt go to all that hassle just to do that.your choice
hope this helps?
