The CNPS10X Extreme is Zalman's first conventional tower heatpipe cooler. It weighs a hefty 920 grams, and comes with an integrated fan and fancy fan controller, as well as mounting hardware for all current AMD/Intel sockets, even LGA1156. Is it extreme enough to be competitive with the top models from Thermalright, Scythe and Noctua?

The DFI LANParty JR 790GX-M3H5 is a mATX AM3 motherboard utilizing the AMD 790GX chipset. DFI is known for the high level of BIOS controls to satisfy overclockers, but it's also an asset for silent PC enthusiasts.

The Fortress FT01 is Silverstone's second uni-body case with lots of other notable features. Low-speed 180mm fans, positive air pressure design, foam-dampened panels, and grommet-mounted hard drives all make this an interesting case for the silent power PC builder.

Intel markets the Q9550S quad core processor as an energy efficient variant of the Q9550. Our comparison seeks to answer two basic questions: Is the Q9550S' power savings enough to justify its much higher price, and how does it compare to an undervolted Q9550?

Zotac is the first to market with a real flesh-and-blood ION motherboard, the IONITX. The version under review, the IONITX-A, is a mini-ITX board with an embedded dual-core Atom processor, Nvidia's ION GPU (based on GeForce 9400M) and a comprehensive feature set. It promises to be an all-in-one solution for small, energy efficient computing with versatile multimedia capability including full 1080p Blu-ray playback.

Single-platter drives are the quietest, according to conventional engineering wisdom, but this truism is not always borne out in reality. The Samsung F2 EcoGreen 500GB desktop drive is a triumph for conventional wisdom.

Rated Gold (read: super Green) by EPEAT, the Ultra SFF M58p is a modern corporate PC from Lenovo. Lean and mean is what we expect, and hopefully quiet, too. A matching Gold (yup, read Green again) monitor, the ThinkVision L1940p LCD monitor is part of our review package.

The SMPPC combines an Intel X25-M 80GB SSD, a Cool'n'Quiet AMD Athlon 64 2X processor, high efficiency DC/DC power conversion and DIY modding on a heatpipe heatsink in a Silverstone TJ08 for a system that is immeasurable even in an 11 dBA anechoic chamber.

The Sileo 500 is a departure for Coolermaster, the company's first case designed expressly for silent PC enthusiasts. How well did CM cover the fundamentals of quiet computing in this modestly priced case?

The Antec P183 is an update of the iconic P182. At first glance, the two cases look very similar, but the P183 has much improved intake ventilation and a redesigned bottom chamber to accommodate Antec's new proprietary CP line of power supplies (as well as longer ATX units).
