Shuttle's $199 KPC K4500 is a testament to ever-improving computer production techniques and design. With its skin on, it looks like a standard breadbox-size system--a type of PC whose interior tends to be a rat's nest of cables, riser cards, and support members. But the K45 manages to combine a small exterior with a roomy interior.

The secret to all the space is the KPC K4500's marvelously compact, integrated motherboard design. The motherboard has onboard HD audio, gigabit ethernet, and Intel 950 graphics--and yet it fits snugly into the bottom of the 11-by-7.5-inch chassis. The cables are neatly routed through the system, the ultracompact 100-watt power supply sits out of the way along the top left rail of the chassis, and the two-bay drive cage holds a single 80GB hard drive. These touches permit easier access to the motherboard's free memory slot, ATA-100 port, and single free SATA-300 port than you get with most full desktops--a pleasant surprise. You can even reach the motherboard's available PCI slot without endangering your finger.
