Due to being a used item, there is a general feeling of use and scratches. I have been using it until recently, and I have confirmed the basic operations, but it is an older generation PC, so please understand that it is sold as-is. (There is no manufacturer repair or warranty) Booting and operation are also slow overall because it uses HDDs instead of SSDs. I do not recommend this to those who are not confident in their PC skills. Please purchase only if you understand. Please consult regarding the price.
