Fuck safety protocols. This is how I want to spend my last minutes anyway.

Can it run VirtualBox?

In my opinion, if you’re buying something to use as a server, you might as well invest in a PC dedicated for the purpose, as it’s a lot more flexible and extendable. You should be able to get away with using relatively low-end hardware and still see a lot more performance than that of a pi.

If your budget is almost nonexistent, replace the harddrive, as that seems to be what’s wrong with your current setup.
