Set Up the Ultimate Steam Box
Build your own small Steam Box PC using Valve's Big Picture Mode
As PC gamers, we’re big fans of Valve Software’s Steam service and can’t imagine life without it. We’ve got a huge library of installed games, all of our friends are on it, and almost every AAA title is released on Steam, making it indispensable. The only “problem” with Steam has been that its interface was designed for sitting 24 inches away, at a monitor, making it incompatible with couch-bound gaming. Valve has rectified this dilemma with its recently launched Big Picture Mode, which slaps a 10-foot interface on top of Steam and makes it easy to control with a gamepad. Since distance and connection issues can get in the way of running your desktop PC on your HDTV screen, we’re going to walk you through a more workable solution. First, we will advise you on selecting a small-but-powerful PC that’s suitable for a living room, then we’ll walk you through selecting appropriate peripherals, and finally we’ll show you how to get it all up and running, ready for Big Picture Mode deployment.

1. Get Yourself a Living Room PC
If you’re like us, you already have a desktop gaming PC that lives in a separate room, semi-far away from your television. Here in San Francisco, we reside in homes so cavernous that oftentimes our living room and bedroom or office are roughly 20 feet apart from each other, and don’t even get us started on our spacious bathrooms and ample parking options (this is sarcasm). Seriously though, space constraints aside, we like to keep our PC out of the living room since it’s big, somewhat noisy (despite our best efforts), and resides under a desk large enough to qualify as a studio apartment in the Bay Area. The living room is reserved for TV watching and Netflixing, and the only gaming it ever sees is on a board, typically. However, now that Steam offers a Big Picture Mode interface that can be controlled from across the room, we’d like a dedicated Steam box chillaxing in our living room so we can play some PC games from our couch.

Falcon Northwest Tiki gaming PC
To accomplish this feat, we had two options—buy or build. Anyone who reads this magazine knows the route we took, but there are also a couple of worthwhile rigs for folks who don't want to get their hands dirty. For the more budget-conscious, Alienware’s X-51 has an elegant and amazingly thin chassis that can be had for as little as $800 (it received a 9 verdict when we reviewed it in our May 2012 issue). If you're willing to part with a bit more cash, Falcon Northwest has a new slimline rig called the Tiki that’s just 4 inches wide (pictured above). The baseline Core i5/GTX 650 combo will set you back $1,600, but Core i7 and GeForce GTX 680 are also options, if you can afford it (see our review in the September 2012 issue). Though both of these machines would look great in a living room, we chose to build a system because that's what we do here, and because we have a perfect template for this task: the "How to Build a Small Gaming PC" story.
