Yeah, if it was a gaming PC it would have no problem doing Nas and steam. I wouldn't bother with kubernetes or docker though. Just use Linux, no need for containers.
Definitely. Just the headache alone of python 3.x here and php version x there and oh boy hope they don't clash is so annoying.
For a simple webhost it makes sense to install bare metal if it doesnt have to scale anyway.
If I need 2 different db versions on the same host for different application stacks it is so easy to just insert a new program.
I think you are right indeed, i had the idea to maybe use the GC for AI stuff and play with it. I would probably go with kube and add the NAS in longhorn (that i already set up)
