Despite its small 4-inch stature, the PC packs much in its tiny frame. Truthfully, it better, what with its $999 (about £617, AU$1,069) price tag.
Rattling around inside are an x86-based AMD 3.2Ghz quad-core chip, 8GB of RAM and 128GB solid-state drive storage. The Piston packs 12 USB ports and can support up to three monitors through mini-DP, HDMI and DisplayPort at up to 4K resolution.
What's more, the Piston can support up to 1TB of SSD.
By all accounts, the system is a PC trapped in a console-sized body, except with the added bonus of modularity. It's this feature that lets users keep upgrading the Piston's hardware overtime, Xi3 touted.
Opting for a more compact motherboard architecture compared to a regular computer, the company plans to release its own upgraded boards and components that can be installed individually as PC technology improves.
A steamy relationship
When the device was first unveiled at CES 2013, the Piston was initially mistaken for the first Steam Box console. Although Valve praised the system, a few months later the digital gaming boutique distanced itself from Xi3 and Piston.
Big whoop you say, but it's on this solid-state drive that you can install your own operating system, including the SteamOS. Perhaps we can take this as a hint that the Steam operating system will be ready by mid-November?
