Well maybe the best custom board of the 1080 have now a watercooling solution from Alphacool http://www.alphacool.com/detail/index/sArticle/21458/sCategory/20582 I just bought the gpu and see that there are no solutions for custom cooling block, but alphacool did a exclusive one for the amp. Great job!
I wish the 1080 wasnt so much here plus the extra $200 just for a good block My 290 is starting to annoy me with its poxy ram voltage being tied directly to the core :\
