Manufacturer: Lenovo Product Name: tiny M75q-1 CPU: AMD Ryzen 5 Pro 2400GE (The original CPU was 200GE, but it has been replaced with this CPU) HDD: m2 nvme 256GB (Replaced with one standard on other tiny models) Memory: SODIMM DDR4 8GB x2 (16GB total) OS: Windows 11 Home (Activated) Additionally, I replaced and initialized a spare M2 nvme, downloaded the Windows 11 ISO image from the MS site, created a boot image using Rufus, and performed a fresh installation of Windows 11 Home. *The latest drivers, etc., have not been installed, so it is in the state immediately after OS installation. *Even after a fresh installation, the information is registered in the BIOS, so it will be automatically activated. (See image) *The Windows login ID/password will be provided via message. *It seems that the 5th USB port on the rear is not recognized? (It may be improved by installing the latest chipset driver from the AMD site...) *If the buyer wants to restore the OS to its initial state after receiving the product, the environment can be cleared by running the sysprep command with administrator privileges. *Recently, DDR5 memory prices have been rising, how about a reasonably priced DDR4 PC? What will be shipped is: The main unit + power adapter. There is no original box that this product came in, so I will pack it in a suitable cardboard box. Please understand the above before purchasing.
