green trend looms ever larger over the consumer electronics industry, HP is taking full advantage of the opportunity by unveiling the environmentally friendly rp5700 slim desktop PC. The company toots its own horn by boasting about the Electronic Products Environmental Assessment Tool (EPEAT) Gold award that the machine has garnered, and we'd assume that building it from 95-percent recyclable components and packing it in a box made from at least 25-percent post-consumer recycled cardboard had something to do with it. Additionally, the unit sports an uber-efficient power supply and comes with "an optional solar renewable energy source" to extract juice from the sun. As for hardware, you'll find Intel Core 2 Duo chips up to 2.13GHz, up to 4GB of DDR2 RAM, SATA hard drives as large as 250GB, optional RAID 1 setups, and your choice of operating system. Of course, the EPEAT Gold-certified machine steps it down to a Celeron 440 CPU with 512MB of RAM, and while this particular configuration will start at $817, other options are available today from $648 right on up.
