I haven’t seen anyone suggest Bazzite here so I will. Especially if you like racing titles, compatibility with most racing peripherals have better support under bazzite as its goal is to support the most devices it can while steam OS is purpose built for a few specific devices.

If you’re savvy enough to, check out some channels like eta prime on YouTube. Maybe that can inspire your purchase.

I personally run a minisforum BD 775Si motherboard with a mobile ryzen cpu in conjunction with a Radeon 7800xt sapphire nitro + as my Bazzite box for the past two years now and it’s been a pretty stellar experience.
