Swiss Army Knife alternatives
Want a diminutive home-theater PC? How about a cheap, super-compact gaming rig for LAN parties or your dorm room? See below for suggestions on how to augment the Pocket Swiss Army Knife.

Processor
Believe it or not, the Core 2 Quad Q9400S has the exact same 65W power envelope as the Pentium E6300 despite featuring an additional two cores, more cache, a faster front-side bus, and a clock speed that's almost as high (2.66GHz vs. 2.8GHz). As you'd expect, Intel doesn't exactly give those things away—$300 ain't cheap for a Core 2 Quad at this point. Still, the tight power envelope lets us cram a lot of computing power into a very small space, which might be invaluable to some users.

Graphics
Our enclosure has room for bigger graphics cards, but we think PNY's GeForce 9800 GT EE will deliver adequate gaming performance without making the Pocket Swiss Army Knife too hot or too cramped. This card is based on a slightly lower-clocked, more energy-efficient version of the regular 9800 GT design—"up to 30% less energy needed," says Newegg—and it has a relatively short circuit board with a single-slot cooler. Too bad about that Flashdance-style sticker on the cooler, though.

TV tuner
If you want to turn the Pocket Swiss Army Knife into an HTPC, then AVerMedia's AVerTV tuner card should work as well as with our Sweeter Spot and Double-stuff Workstation. Because our recommended mobo only has a single PCIe slot, however, you'll have to choose whether you want a TV tuner or a discrete GPU. (Any PCIe x1 card like this one will happily function in the mobo's PCIe x16 slot, by the way. Such is the magic of PCIe.)

Storage
WD's 1TB Caviar Green will complement an HTPC spin of the Pocket Swiss Army Knife better than the 640GB Caviar Black. While it's not quite as fast, the Caviar Green has considerably more storage capacity and lower noise levels.

A Blu-ray drive seems like a useful addition to any HTPC nowadays. We looked hard for a slim-line model, but since we couldn't find one that was either in stock or had good user reviews, we went for the next best thing: Plextor's PX-B310U external Blu-ray and DVD reader. The PX-B310U might look a tad bulky next to that Mini-ITX case, but it's relatively affordable, and it comes with playback software in the box. The two Newegg customers who reviewed it sound pretty happy, as well.
