However don't forget that when selling a product, lots of other costs arise. E.g. you'd need FCC certification (around 10k USD for intentional radiators) and make sure that no other standards are violated (mainly regarding mains voltage). The plastic case mold is another 3-5k. Then some margin for returns, marketing, etc.. It's a niche product, so the fixed costs make up a big part.
If it's popular someone will sell a simple DIY kit for 20$ and an open-source server. But I doubt there's much demand.
