This is a Mac mini with a compact design. Specs: ・CPU: Apple M1 ・Memory: 16GB ・SSD: 256GB ・Model Number: A2348, Z12N000BN Purchased new and used in a university lab for 1 year and 7 months. I am selling it because I don't use it much anymore after graduation. There are absolutely no problems with the operation, and the data has been initialized. It was only used indoors, so there are no noticeable scratches or stains. There are some minor scratches and stains on the box, so please refrain from purchasing if you are sensitive to these details. Includes power cable, instruction manual, and original box. Thank you for looking.
