For 800 bucks, let me see what I can do:

Im assuming America, and do you need a monitor, keyboard, and mouse.
Also what about OS?
 
Yes. I live in America.
that $800 is only for the desktop or CPU itself. I already got the monitor, keyboard and mouse. :)
OS = ?? I dont know the meaning of OS. sorry.
