Nice....
a18kiska - Im running the same 4u case as you on my 6th 8gpu build now..... Firstly sweeet build can i ask you a few questions...
What rack rails are you using for the 4u mining racks?
Whats the config of the 3 front internal fans blow out? or blow in? Take it you upgraded these? I went 3000rpm for those.
Whats the config of the AC Infinity using about each miner? Is the lid off? and what direction is the airflow?
Cheers
