I built a new PC workstation from parts.
I am just formating the first hard drive as I install Windows XP 64 bit on my homebuilt PC. I used an Asus motherboard, 8 GB of RAM, and an Intel Wolfdale power efficient processor. It has an e-GeForce 8500 video card with 1 GB of RAM. I have a new LG 19" widescreen monitor for this system. The monitor uses 36 watts for power. I also used a Seasonic 500 watt 80+ power efficient power supply. It seems to be working and is fairly quiet. This new homebuilt PC is fairly green in its power efficiency.
