Set Up the Ultimate Steam Box
2. Prepare Your Rig
The rig we built for this job splits the difference between a full-powered gaming machine and a small form factor PC. We know—technically, it’s a small form factor PC since it has a tiny Mini-ITX motherboard, but that board houses some kick-ass components, including a water-cooled Intel Core i5-3570K processor, a 240GB SSD and 3TB HDD, and an overclocked GeForce GTX 670 from MSI. In our benchmarks, this little rig cranked out 76fps in Batman: Arkham City at 2560x1600, which is more than enough muscle for gaming on our TV. That’s one hell of a PC, and the fact that it’s not any taller or wider than a roided-out Chihuahua is icing on the cake.

3. Choose the Peripherals
As desktop commandos, we know exactly which mouse and keyboard combo we usually prefer, but that all changes when you move to a softer, more comfy location like the couch. We needed a keyboard that was light and wireless, and we decided against a mouse simply because neither our legs nor our couch is flat enough to provide an accurate mousing surface. We also needed to select a gamepad that works well on a PC, and it's slim pickings these days as most gamers just use a mouse and keyboard.
Keyboard
To satisfy both our mouse and keyboard needs we went with the sublime Logitech K400 Wireless Touch Keyboard (below)—
not to be confused with its predecessor from the 1980s, the Invisible Touch. The K400 is incredibly light but provides comfortable keys and a surprisingly accurate touchpad with vertical scrolling support that makes browsing the web and navigating Steam's interface a cinch. The keyboard's 30-foot wireless range is more than sufficient, and its slim profile comes in handy when we need to stow it inside our entertainment center. We also like the fact that the included AA batteries will last up to a year; we just have to remember to turn off the keyboard when not using it.

Game Controller
We debated for quite a while over which game controller to choose before settling on an old standby, the Xbox wireless controller for PC. We like that it's comfortable, easy to set up, and it works perfectly. We could have saved some money by going with something from Saitek but we like the build quality and heft of the Microsoft controller. Say what you will about Microsoft’s ability to craft a touch-based OS, but the company knows how to build a peripheral, that's for sure. The wireless dongle is also easy to tuck away in our rat's nest of cables.
