Downsizing Your Rig? Build A Mini-ITX PC
Armed with an EVGA Z77 Stinger, a Bitfenix Prodigy, and a load of Corsair kit, Mark sets out to build a small gaming rig with big performance.
The Parts
With my mind made up it was time to choose the parts. I had intended to recycle a lot of stuff from my previous rig, but the limitations of Mini-ITX meant some things had to be replaced. Unlike other builds where you might start with what motherboard and processor you want, a lot of what you can do with Mini-ITX is defined by the case you choose. There are a lot of Mini-ITX cases to choose from these days, but few are geared up for high-performance computing. Many are designed to sit under a TV, or attach to the back of a monitor, giving you little room for long graphics cards or multiple hard drives.
After running down the options there were really only two cases that had the space I needed to house an adequate amount of kit: Silverstone's SUGO range and BitFenix's Prodigy. The Silverstones are small, Shuttle-style cube cases, which come with the added bonus of an included power supply. However, while they will fit a full-length graphics card, there's not a lot of room for much else. There's space for only two 2.5" drives, and only one 3.5" drive. Plus, water-cooling isn't really an option, at least not without extensive modding.
The Prodigy was the obvious choice for my needs. Not only does it support a vast array of cooling options thanks to multiple fan mounts, but it also supports a lot more drives--up to nine if you aren't using a long graphics card. In my opinion, it looks a lot better too. Other great features include support for full-size ATX power supplies, which are ideal if you need the extra power for overclocking, plus there's lots of room inside for big CPU heatsinks, should you wish to use one. The only issue you might have with the case is its size: it isn't the smallest Mini-ITX case out there, but compared to something like the 650D, it's positively tiny.
For the CPU I decided to reuse the Intel Core i7 2700K from my last build. Intel's new Ivy Bridge chips do have the added benefit of support for the new, faster PCIe 3.0 standard, as well as slightly lower power consumption, but for me its performance boosts weren't quite enough to consider splashing out on a whole new CPU. I did, however, need to get a new motherboard. There isn't a whole lot of choice when it comes to Mini-ITX, particularly in the performance category.
Gigabyte makes a value-orientated range, but even on the Z77 model, overclocking support is weak at best. That left ASRock's Z77E-ITX, and ASUS's P8Z77-I Deluxe. Both have received rave reviews for their performance, especially ASUS's board, which--with its unique 10-phase power Digi+ VRM daughter board--should overclock like a champ.
But just when I thought I'd made my mind up, enthusiast favourite EVGA released its take on Mini-ITX with the Z77 Stinger motherboard. I've had some experience with EVGA's graphics cards and most notably its monster SR-2, dual Xeon motherboard that we used to build the Greatest Gaming Rig on GameSpot. Both times I was impressed with the build quality and performance of its devices. And--from a purely superficial point of view--the understated black and red colour scheme was way more appealing than the neon blue of the ASUS.
The EVGA Stinger has a similar feature set too, including four SATA ports (two 3G, two 6G), support for up to 16GB of 2133MHz DDR3 RAM, 7+1 Phase PWM, two e-SATA ports, and up to six USB 3.0 ports. What's missing is the included WiFi card, which is a disappointing omission at the board's higher price of £160, though there is a Mini PCI-e slot on the motherboard for adding one yourself.
The rest of the rig was an easy shop. For the GPU I settled on an Nvidia GTX 680--a bump over the 570 I used last year--and for cooling I decided to reuse Corsair's excellent 240mm radiator H100 liquid cooler, which performed brilliantly for me over the past year. Some things, however, had to be replaced. The RAM, which was originally 16GB spread out over four sticks, had to go. With only two slots it had to be replaced with two 8GB sticks, for which I went with Corsair's mean-looking performance-tweaked 1866Mhz Dominator Platinum RAM.
The PSU posed its own problems. While Bitfenix's Prodigy case supports full-size ATX PSUs, it only supports those with a maximum length of 160mm. That meant the Corsair 850HX I'd been using wouldn't fit. Instead, I replaced it with a fully modular Corsair AX 750 PSU, and paired it with a red braided cable kit to match the motherboard. For storage I went with a Corsair Neutron 240GB SSD, rated for 555 MB/s sequential read and 370 MB/s sequential write, and one of Samsung's new 840 Pro SSDs, which are rated for 540 MB/s sequential write, and 520 MB/s sequential read.
The Corsair would be used for storing the Windows OS, as well as a few key programs and games that I played often. The Samsung, with its superior write speeds would be used for a Hackintosh partition (that is, installing Mac OS X onto standard PC hardware), on which I do most of my audio and video work. I don't store a whole lot of media on my rig--a 4TB home server handles those duties--so I went with a pair of single platter, 500GB 7200RPM Hitachi Deskstar 7K1000.D drives.
