Well, again, I've changed! This configuration support full-length reference GPU! It wasn't necessary to change the fan as well, but, why not? I want to try the thinner rad+fan config to see how it performs! And everything is very easy to swap.
And there was space for a T-connector to fill "easily" the system!
(Maybe the GPU in the loop will be possible as well??)
I'll post soon temps under stress! (But also here, with the ASUS Z390 ITX. the VRM reach the maximum. The initial option was to use the ASrock Z390, but I don't know why, the MB doesn't turn on with the G-Unique. Is the only brand. I've tried the previous Z370 ITX as well, and nothing. Maybe is some safe option in the BIOS??
