This is the 512GB model, which features:

Storage: SSD with 512 gigabytes of storage

Random Access Memory (RAM): 16GB RAM

Screen: 7 inches, 1280 x 800p resolution, 60hz (60fps / frames per second), etched (anti-glare) glass

Operating System (OS): SteamOS - a version of Arch Linux, modified by Valve

This unit is in excellent condition, working exactly as well as it did out of the box. Feel free to request additional pictures if you want a clear/better view of a particular area of the device. As you can see, it features all of the additional accessories which were exclusive to this model, such as a higher quality carrying case, carrying pouch for the charger, and a custom microfiber cleaning cloth. It also includes the original (OEM) charger from Valve, specifically made for the Steam Deck. One unique feature of the original 512Gb model, which is not found in the 256gb or 128gb models, is the etched glass screen. This additional step in the manufacturing helps to reduce glare when looking at the screen, and is a great feature for use in various environments.

As stated earlier, the device is in excellent condition. I say this not only to refer to the working condition of the device, but also to the cosmetic. It is my hope that, upon receiving this Steam Deck, you feel as though you are getting a brand new unit. I have included nearly all of the original packaging to aid in this experience. This listing includes free shipping.
