There is one being made called the Xi3 Piston, starting at a low price of $1,000 or $1,750. Which come equipped with 8GB of RAM, a 3.2 Ghz Quad Core processor.
Not a pretty price. Hell even a $600 gaming laptop has better equipment. 
Fuck, people buy consoles because they’re cheap, No sense in turning them off at the price tag.
I hope people don’t confuse these unofficial ones with Valve’s Steambox.
