Are you planning to use this just for yourself. Or, are you planning to start a SaaS company from your home? A flood of requests, bots, or even a ddos attack can cause issues with your internet connection. If you use that same connection for work for example that can be a serious issue. Unless you have a static IP address you'll have to deal with the IP changing. If there is a vulnerability in your express app, it could lead to the compromise of other machines and other parts of the network (unless this windows machine is isolated from the rest of your LAN.) Just things to consider, probably not deal breakers!
