Right, I think it is fine to run a normal website on the Internet and also
make it available as an onion site by running Tor on the same computer.

It all comes down to what security goals you have in mind. If one of
your goals is to protect the location of the website so people visiting
it cannot learn where it is, then you have many more things you ought
to think about.

But for your situation, it sounds fine. For background you might enjoy:

These phrases "Tor server" and "Tor node" are ambiguous. You might enjoy

Running a Tor relay can use quite a bit of memory depending on how much
traffic it's handling. Running a Tor bridge generally means you're
handling much less traffic, and so the memory footprint is much lower.
And running an onion service (aka hidden service) is usually very low
memory footprint too, but it depends how popular the service is.

Hope that helps,
