Thank you for viewing. I am selling an HP Z230. It's an old PC, but I bought it new and used it with care. There are no noticeable scratches on the exterior, and the bottom is relatively clean. There is some dust inside, but I haven't done any aggressive cleaning. Please check the photos. It is equipped with two NVIDEA NVS 315 graphics cards, allowing for 4-screen use, but I used it with 3 screens. The configuration is 17 inch + FullHD (vertical) + FullHD (vertical). You can configure the layout and rotation using the NVIDEA controller. Please make your judgment based on the photos for the rest. Shape: Tower OS: Windows 7 Professional 32bit CPU: Intel Core i3 Memory: 4GB Storage type: HDD Storage capacity: 1TB Accessories: 2 dedicated display cables 1 power cable (unused) 2 DVI to VGA adapter 1 DVI to VGA conversion cable I have confirmed the operation, but since it is a used item, there is no warranty. Please understand that we cannot accept cancellations, returns, or exchanges. I hope that someone looking for this kind of product will find it. Thank you.
