Get a Raspberry Pi. Newer models have wi-fi. Then you can host all kind of stuff. As long as it is for your own use, you don't need that much computing power. As far as software is concerned, the type of physical connection doesn't matter. Wi-fi stability can be excellent or it can be super frustrating. Depending on your circumstance.
Get one and try it. Learn by doing.
Try to keep expectations low and you'll live longer.
