The Minisforum UM890 Pro with AMD Ryzen 9 8945HS is available as a barebone, which means that it is supplied without RAM, storage drive and operating system and you have to retrofit these components yourself. However, there are also pre-configured versions with RAM, SSD and Windows that are ready to use. If you buy the barebone version, you still have to install RAM, storage and an operating system before you can use the PC.
