The ROG Ally has been out for some time now so we're finally seeing some 3rd party accessories for it like this carrying case from Hounyoln. The official ROG Ally carrying case has great aesthetics but it's just overpriced in my opinion. So if you're in the market for a carrying case this would be a great option for you with the ability to prop the Ally up and it has plenty of storage space for anything you might need. Let me know if you have any questions about this in the comment section.
