You have to take MLID with a several large grains of salt. He gets a lot wrong, and when he does, he deletes the corresponding videos. There are Reddit subs that won't allow links to his videos for that reason. Valve has also said that it won't be console-type pricing, more like the pricing of a decent SFF PC.

Having said that, it would be great to see the GabeCube come in around the prices he's guesstimating. I hope it finds great success.
