HaaS was my goal with http://www.gameref.io (selling/renting to eSports tournament organizers) -- unfortunately, and as others say in this thread, I couldn't raise enough money to move out of the prototype/MVP stage. Hardware is hard, and even with working my butt off to get covered by PC Gamer, Tom's Hardware, Vice, and dozens of others, I couldn't get enough nibbles.

C'est la vie.
