Includes the main unit and power cable only. I replaced the internal HDD with a Samsung SSD 1TB 860QVO myself. I'm selling this because I got a junk M1 iMac, but I was able to use it without any particular complaints for things like browsing the internet, watching videos, and playing games that aren't high-definition (like Stellaris) until I started using the new PC I bought. I think it would be difficult to use very heavy creative software, though. Operation is not a problem, but since I took it apart once, please understand that it is sold as-is, with no returns. Thanks to the SSD replacement, it can still be used actively if you're not trying to run very heavy software. There are no major scratches, but there are some scratches and dirt due to aging, as it's a 2015 iMac. Thank you.
