Enquired about S5 boards and controller. About $500 to get part's but no warranty if put in C1 case.
However...
This is what they said at the bottom of the email;
"if you are in no rush we have some nice things prepared for near future so stay tuned."
So I am guessing I am going to get rid of my hash baords but keep the c1 case and do a watercooled single s5
I don't see them doing water cooled again. I could be wrong on that. But I'm thinking air cooled in future.
But you are right the parts could be used to make S5 boards water cooled, I know I have seen it on forum before.
