There's a few ways. Already have an old pc hanging out somewhere? Good - don't buy anything new. Run the HTTP services from there and set up port forwards in your router, and DNS with your domain registrar (or set up cloudflared as other commenters noted). You're done. Step further, you can go with a RasPi or a similar SBC, but just be aware running with ARM can have its' own challenges. I'd recommend a cheap x86_64 machine from ebay, such as an HP t730 plus thin client. Native SSD support, higher/upgradeable ram capacity, and better IO would all come together to make a better server machine. The RasPi would win out on a few points (power draw, memory speed), but in this scale it likely wouldn't be noticeable. Lastly - don't be afraid of cloud services. A GCE/EC2/vultr/hetzner server can get you pretty dang far for just a few bucks a month. Also, this makes it easy to get some exposure to infrastructure provisioning tooling (I prefer Terraform and Terragrunt) and server configuration management tooling (I prefer ansible).
