The Compact Fusion Reactor
Fusion that isn't just a load of hot air
Sandy Bridge's troubles don't affect all categories of PCs. In the price range of this lilliputian build, only uber-cheap, low-power CPUs can compete—and there's some new hotness from AMD that shakes up this segment almost as much as Sandy Bridge does more expensive systems.

Processor, motherboard, and graphics
Integration is the name of the game with AMD's new Brazos platform. Much like other Mini-ITX Brazos motherboard we've looked at, ASRock's E350M1 incorporates a Zacate processor with dual 1.6GHz cores and DirectX 11 integrated graphics on a cute little 6.7" x 6.7" circuit board. The only difference is that, with a $109.99 asking price, the E350M1 is quite a bit cheaper than the competition.
Don't let the low price fool you, though. The E350M1 has a surprisingly complete array of features: one physical PCI Express x16 slot, four internal Serial ATA ports, six USB 2.0 ports, one eSATA port, and a choice of DVI, HDMI, and VGA display outputs. We wish the heatsink covering both the Zacate CPU and its Hudson I/O hub weren't crowned by a tiny fan, since such small fans can and often do get noisy over time, but active cooling seems hard to avoid among Mini-ITX Brazos mobos right now.
Unfortunately, the E350M1 unexpectedly went out of stock as we were writing this guide. We think it's almost too good a deal to pass up, but if you can't wait, check out the next page for a slightly pricier alternative mobo that's actually in stock.
DDR3 prices have sunk so low that, even for a bargain-basement build like this one, we'd be remiss not to include 4GB of RAM. Since Zacate doesn't have a dual-channel memory controller, we've gone with a single, high-density 4GB module, courtesy of Kingston. A dual-channel kit would cost about the same, but it'd fill both of the ASRock board's DIMM slots. This way, if you ever feel the urge to upgrade your $300 pint-sized PC with 8GB of RAM, you can. Neat, huh?
Just remember to install a 64-bit operating system if you want to use 4GB of RAM or more. 32-bit OSes have enough address space for 4GB of RAM, but that figure is an upper limit for all memory in a system—including video RAM, which will matter if you ever feel like chucking a real graphics card into the Compact Fusion Reactor. In practice, 32-bit versions of Windows will only let you use 3 to 3.5GB of actual system memory, and they'll normally restrict each application's RAM budget to 2GB. Workarounds exist for 32-bit Windows, but Microsoft says they can hurt compatibility; it advises that folks run a 64-bit version of Windows instead. We're inclined to echo that recommendation. Check out our OS section on the second-to-last page of the guide for more details.
Our chosen enclosure doesn't have room for full-sized hard drives and optical drives, so we've had to opt for mobile offerings. On the mechanical storage front, WD's Scorpio Black 250GB looks to us like a sensible choice, considering its 7,200-RPM spindle speed, low price, five-year warranty, and overwhelmingly positive user reviews on Newegg. If you think 250GB is cutting it a little close, check our alternatives on the next page for a higher-capacity option.
On the optical side of things, Samsung's slim SN-S083F drive appears to be an equally capable candidate, with DVD burning capabilities, Serial ATA connectivity, good user reviews, and a surprisingly affordable price tag.
Enclosure and power supply
And now, for a teeny little case to tie all of this hardware together. We've used boxy Mini-ITX cases before, but Antec's ISK 300-65 takes the form factor to the next level, featuring an external power-supply brick and much slimmer dimensions: just 12.9" x 3.8" x 8.7". That leaves room for only a pair of 2.5" hard drives and a slim optical drives, but it makes for a svelte PC that's easy to tuck away out of sight. Antec still provides space for a low-profile expansion card, too, which will come in handy as we explore home-theater-PC expansion in our alternatives section on the next page.
