the reason i dont use them is purely because there have been a LOT of issues with these boards and the onboard power connection ...
through various forums ( uncluding the asrock one - which doesnt have much to do with the mining arena any longer ) the boards have been brought up as being a way of warming your house by means of fire rather than hot air ... apparently that if the sockets and cables supply dont get the power they require for any reason - they ignite in the worse cases ... the least cases ( which is the common one ) is that they burnout your cards or the board itself ...
If yours are running well - then kudos mate

...If you use this board with 6 non powered risers, it's very important to blug in the extra 2 power slots I marked in the picture. It can also be good to add a couple of cards with a 6pin power connector.
