havent gotten my head arounde the new ryzen cpu's but 1 week before the ryzen relese i build my own pc for the first time :
pcpartpicker.com/list/zb2CkT
i must say it runs like a dream... i had the go a bit lower bc of the taxes here in denmark that makes the parts quiet more expensive to buy.
i like your build idears and i just wanted to share my new build
