I bought myself a server with 40TB of storage and then gave 10 of that to a iscsi drive which I mount from my gaming pc. So I now install games over my network and play them from there. It helps when you have over 150 steam games and want to install them all.

So if the rare occasion appears when I actually play one of them I can do so instantly.

It only costs 1000€ and a few weeks of setup.

Easy can recommend everybody
