Delivery perfect in one day, perfect packaging, pre-installation of the system in Windows 7 mode for people not used to Windows 8. Product of very good quality for the price. Too bad that many have paid taxes on it. No noise from the tower. Very happy with this purchase urgently for a replacement of a computer breathless. Perfect computer for everyday use on all levels and adapted to the "gamers". If a fault occurs, I would change my review thereafter. But for now, it's just perfect !!!
