Hi, would be running 2 r9 380 and an i5 4440 , yes I know wc may seem abit overkill for these but its more about temps/noise for me + I really enjoyed my last custom loop (its all about the looks really) also going to use a 360mm at the top instead of a 240mm as its not much more expensive so would be 480mm total now.
Also, this is all planning at this point so I don't even know if there is blocks for the 380s, in which case i'd either go cpu only or use nzxt g10s for the gpus
