I might be moving into a house with solar in the next few weeks, would it be worth building a mining PC since electricity will be close to nothing? Or can I use my gaming rig to mine when I'm not playing?
It really depends on your graphics card. You can mine ETH and set it up to automatically mine when you are not using your computer. It will generate a lot of heat in the room from the graphics card running full tilt. It is also hard on the graphics card, but a graphics card gets out dated typically before it gets used up anyways so I'm not sure it really matters. You can search the hash rate of your graphics card and fiqure out how much it will generate per day based on the current value.
