@Radim Razzak - search on the supermicro site for your country maybe you can find a local re-seller in your country that might be cheaper then ebay or amazon and you have actual warrenty from a local place plus a possibility to get ram from them as well. I searched for the boards on ebay and amazon first the only available in Europe was in London and it costed 750 pounds without shipping not to mention the taxes my country would make me pay if I order. Finally found local re-seller on supermicro website and it costed 530 euros...
Thank you for the hint, you were actually right! I found one re-seller with really competitive prices. And as for the Platinum ES chips, do you by any chance know what is the difference between "Intel Xeon Platinum 8160 ES QL2M" and "Intel Xeon Platinum 8160 ES QL1K"? Which one is the newer stepping? Thanks
