How do I know?
I ordered one and a salesman called me and let me know that I should get something else to keep the price over 1500 to keep the rebate. Instead of the hard drive caddy and graphics card upgrade ($150 for both) I got a 180GB solid state drive as my harddrive and I keep the disc drive intact.
