Ask HN: Uses for Idle Gaming PC?

Last year I had built a pretty beefy gaming PC to use for game development and playing games.

Fast-forward to today and I'm not developing or playing games that much at all, so this PC sits idle most of the time.

What are some things I can have this PC do in the interim? I don't pay electricity and extra heat would be beneficial during Canadian winter anyway. Right now it serves as a Storj node and Folding@Home machine, with some crypto mining in the past which I've stopped due to pitiful returns.
