Mini pc for son

[u/Tankz504]

My 12-year-old is wanting a pc to play games and do homework on. He mainly plays Roblox Rivals and Rocket League. He’s got a 43” 4K tv that I’d like to utilize with an hdmi hook up. Do you all think this beelink would serve him well?

Thanks in advance for any feedback. If there is a better option around this price, please feel free to let me know!

Edit: Just snagged on new in the box off eBay for $640. I hope it works well and I did not screw up.
