Jens, could you please consider producing one or all of the additional A4000T module cards.
They are simple designs, they have no expensive custom chips, their scematic are available and they are very much wanted for those who have once bought empty A4000T PCB and assembled it themselves. There were many empty A4000T PCBs available once in ebay, so there seems to be many who are missing and want module cards for their motherboard.
Because of this some people may pay more than 600 euros to get all of these. That is just when you get a working basic A4000 with a price like that. See recent ebay listing
