ROG Ally Z1 Extreme with modified dual battery and dual storage

ROG Ally device, 2023 version, purchased from Jarir with all original accessories and box. The device is clean and I've been careful in using it. The device has been modified twice: modification for dual battery 74Wh, and modification of the M.2 port for larger and cheaper storage expansion. I'm including a 1TB drive as a gift to the buyer. Asking 1800, negotiable with serious buyers. Reason for sale: Need money, God provides. Note: I can install any operating system the buyer wants. I recommend Bazait for longer battery life and better performance.
