Gateway is rolling out the first of its business desktops that use the BTX model developed by Intel.

Compared with the traditional ATX model, BTX puts all the hottest components—from processors to graphics cards—in the center of the chassis, where they can be cooled by a front-to-back airflow. The result is more reliable, more energy-efficient and quieter PCs that offer improved cooling capabilities. Earlier this fall, Gateway unveiled consumer desktops featuring the BTX chassis. Eventually, all Gateway PCs will feature the BTX chassis, officials said.

Gateway's E-6300, priced starting at $989, offers Intel's Pentium 4 chip with Hyper-Threading, Serial ATA hard drives, up to 4GB of DDR2 (double data rate 2) memory and integrated Ethernet.

Gateway last week announced two desktops with the ATX chassis, the value-oriented E-2300 and mainstream E-4300.
