Never used an ASRock board before - I bought it simply because it was good value for use in a media server - I didn't have much in the way of requirements so I didn't want to spend hundreds on a board. This one has been a pleasant surprise, nice quality, I'd definitely consider ASRock for my main system next time I upgrade.
