Dear Customer. Thank you for your feedback and apologize for the issues with your shopping experience. We understand the size and graphics card change issues you mentioned. First, regarding the size issue, we apologize for not being able to fully confirm the size of the All-in-One with you during the shopping process. We will improve our communication as soon as possible to ensure that our customers are aware of the detailed specifications of their purchases before shopping. Secondly, regarding the issue of replacing the graphics card, since you are considering higher RAM but at an additional cost, we have provided you with a graphics card upgrade option specifically for you in order to give you a better experience, so please don't get me wrong. Thank you again for your feedback, we will take your comments seriously and strive to improve our service. Hystou are committed to making the Mini PC shopping experience better for everyone and will do our best. Best regards. Hystou Team
