Hi Rian, Read thread about AV1 computer with interest. Amazed with your results of home building and carbon fibre work. Certainly like to learn more about carbon fibre work as I want a cover for my Submatix breather. I am one of six Submatix users based in Perth Western Australia. We have a lot of experience with Submatix and two of us have had factory training. If we can assist please let us know. Where abouts in South Africa are you based? Geoff
