The noise level is low and the tower is cery slimline, it fits right on top of my desk. The system is very fast and works great! My issue was when I recieved the unit the ports were not lined up properly forcing me to buy a seperate docking station so I could hook the eathernet cable up. Also this only has a set up for 1 vga monitor, but since I added the docking station I can use 2 monitors. Other wise this unit is awesome for the money. My core processing speeds are well above what is advertised. I work from home and this system handles multiple programs at one time like a charm. It is a great value for the price and runs like brand new!!
