Thank you for viewing. I purchased this used in January 2023 and have used it occasionally. I am selling it because I bought another PC and no longer need this one. Model number: CF-SZ6RDYVS OS: Windows 11 24H2 (Upgraded from Windows 10) Core i5 CPU, 8GB memory, 256GB SSD The SSD was replaced with a new one at the time of the used purchase. The BIOS accumulated time was over 6000 hours at the time of the used purchase. Regarding MS Office 2019 Business (includes Word, Excel, and PowerPoint), this was pre-installed in the Windows 10 state. Operation on Windows 11 is unconfirmed, and it will likely be deleted upon reset. Therefore, its operation is not guaranteed. The exterior has small scratches and dents on the top cover in several places. Please check the photos. Please consider purchasing this item, understanding that it is a used product and the above information.
