It's not impossible, however, have you seen what corporations buy for their employees? Saving on upfront cost isn't really part of the equation, it just has to say "dell" and/or "workstation" on it. A large company values long-term support and supply way more than what they'd save by getting a gaming machine.

And besides all that, it's not like the best selling console of all time didn't make money because a (objectively large) minority of owners only used it as a DVD player.
