Setting aside the strange Kickstarter campaign, the likelihood that this will be a (twice) forgotten gaming platform and an endlessly reaching release date, purchasing the Atari VCS—for less than $400 US dollars for an embedded AMD Ryzen APU, RAM, powersupply, etc.—is a great deal. Building a PC with similar hardware puts you well beyond that price and isn't likely going to be as nice as a final product.

I'm not holding my breath for this project. But if you are interested, Atari has lined up partners like Walmart, which means it has to come out at some point.
