Xi3 Piston due in November, priced from $999

Xi3 has detailed its Piston Steam box, which launches in November, giving tech specs, a price and future-proofing options.

The console-like PC comes with a 3.2 GHz AMD Trinity Processor, 8GB of RAM and an 128GB SSD. It can be upgraded to hold two 512GB mSATA SSDs for a total of 1TB. In the future, it will be upgradable with new I/O boards.

It natively supports triple monitors thanks to 384 graphics cores - a Radeon 7000-Series GPU.

It comes preloaded with a few games, and supports a variety of controllers so you can choose whether to play on the couch or at your desk. Xi3 is pretty pleased with the energy consumption levels, which it boasts are lower than household lightbulbs, and won't cause overheating.

Due on November 29, it's just 4" long on each side and will cost you $999.

More details are available on the Piston's product page.

Piston is unrelated to Valve's own Steambox, which will go into beta soon.
