Looking for a couple mini pc's for kids gaming

I've got two little ones that are starting to outgrow their chromebooks and playing around with same (light?) gaming, such as: world of warcraft, subnautica, and valhiem.

Looking to buy two and room is a premium so I'm thinking about going the mini pc route, each with a 1080p monitor.

The mini pc's don't to run the latest high intensive game in ultra mode, but I'd like for the above games to be very playable and enjoyable.

Any recommendations with a budge of $300-500 per PC?
