I looked into to using a laptop as a router a while back and decided against it. From what I read, the chip is designed for bursts of processing and isn’t designed to be under constant load like a router would be. That means the fan will always be running an you risk overheating, fan failure, and high power draw.
That’s my non professional recollection so take it with a grain of salt.
I self host on windows. It just happened to be what I had on the box. Then I got started with docker. So that was great. When I have the time, I hope to switch to unraid, but need the time to be open enough to deal with the problem that will arise in getting the system set up just right.
