At work I use the 420 and 840, so when I saw the 440 for sale I immediately wanted it.  It is a powerful system.Things to look out for.  The video card should be upgraded or replaced.  The card is adequate for low functions but for a system like this one, recommend replacing the video card so you can get the use out of it you deserve.  It is loaded with 32GB Ram, and more USB 3.0 ports you could ever want.  I added a Bluetooth card for the speakers and upgraded the mouse and keyboard from what was provided.  I gave it 4-stars because of the video card.
