How To Build A Small Gaming PC Way back in December 2010, we built an awesome Mini-ITX gaming PC dubbed the Wee Ass-Kicking Machine. It featured a Core i7-870 CPU, a GeForce GTX 460 GPU, 4GB of DDR3, a 1TB hard drive, and a 120GB SSD-all crammed into a Silverstone SG07 chassis not much larger than a shoebox. The total cost? Around $US1600 (at the time). It's, uh, been a while since then, though, and I thought it was high time we built another Mini-ITX gaming PC. This one's not quite as small, but it's got a lot more oomph. We're using the BitFenix Prodigy , which has room for a full-size ATX PSU, scads of hard drives, and even a 240mm radiator (if you swing that way), while still being small enough to be lugged around by its convenient carrying handles. Let's See What Fits Just because this is a Mini-ITX build doesn't mean we're messing around with integrated graphics. Pah. Pshaw. And other expressions of contempt. Nope, when we build a gaming rig, we use a real discrete graphics card. This time we're going with an MSI GTX 670 Power Edition, which is factory overclocked but still sips power like the rest of the Kepler lineup. The most important part of the build is the case. The BitFenix Prodigy is large for a Mini-ITX chassis, but that just means there's room for more stuff. It can accommodate a full-size PSU (although 140mm is really the maximum depth), up
