Foundry Hosting Questions

I recently set up a 4tb home server (just some two slot 200$ QNAP, nothing fancy) and have a 10mbps upload speed and am finding it a bit confusing to determine if I can host from that device successfully or I should skip it and just host from my actual PC or reach out to GCS or AWS instead. I'm new to Foundry VTT so I don't know what to expect for load from 6 or so people at a time accessing a game instance. Obviously I don't want to spend money every month that I don't have to on server fees if mine can suffice.
