I have bought this PC following the lightning that grilled the former. The price / quality ratio is impeccable and I think I will have paid more in the assembling myself, especially with Windows 7 Pro installed and supplied with dvds. The tower is very beautiful and well made. Everything is assembled perfectly. The seller is very serious. The shipment was fast, as always with Amazon, and the packaging is nickel. Namely: if you want to add a hard disk or other, you will be forced to remove the processor fan. To conclude, I am delighted with this purchase.
