got bored of my solar powered calculator so i built something on the cheap. power draw is nice also, somewhere around 40-60 watts! overclocked steady to 4.8Ghz. the gpu is clocked at 950Mhz..Prime95 4.8Ghz stable max heat;48°C. ambient temp 34°C. Cpu fans and System Fans at 100% yet quiet while watching a movie.
