I’ve recently picked up a secondhand Lenovo ThinkCentre Tiny PC which ultimately I plan to use as a home server for a variety of functions (media server being the main one) but I don’t need to use it as a main desktop.

It currently has Windows 10 installed. It has a decent sized SSD but no optical drive. I want to install a suitable Linux distro on it. What’s a good Linux distro for my needs? And what’s the best way of doing a scorched earth on the Windows install and replacing it with said distro?

I’m not entirely a Linux noob - I used to work on Xenix and later Red Hat Linux, but that was 30 and 20 years ago respectively!
