Their Ultra series motherborads were legendary for the time. Namely AN7-Ultra for AthlonXP and AN8-Ultra for AMD64.

Besides being able to overclock anything to its absolute limits, they have repurposed a keyboard microcontroller to monitor temperatures, fans and voltages on the board (aka uGuru), providing unparalleled flexibility and reliability when no other company was able to provide at that time, and after them.

Setting fan curves for temperature response was great and allowed me to run AthlonXP at 2200Mhz (200x11@1T) without excessive noise for normal tasks.

Their AN8 Ultra provided a rock solid foundation for my AMD64 system, too.

None of my capacitors have leaked/bulged despite using systems under relatively heavy load.
