Run a VM (even if it's slow) or rent a cheap VPS (lowendbox.com is my go to), you can get a cheap Linux server for maybe $5 a month.

And you know what ? I highly advise YOU DO DAMAGE the system! many times over, and over. This is the best way to learn. Do experiments on that Linux, one at a time. You ARE going to break things, and that's okay. Learn how to fix them - you'll be a master in no time. Yes, this means running "rm -rf /", see how the system reacts to that (keep a shell session open, but also try opening another session, such as via SSH). Try to fill up a drive, fill up memory, see what happens etc etc.

Cheers
