got my chassis', motherboards, psu's etc. today.   I did not receive the 24-pin ATX jumper so I had to fashion one out of a paperclip.   Also, my ASUS Strix 1080ti's are too long to fit in the case with the fans installed.   I haven't tried my MSI Duke 1080tis but they are even longer I think so no chance.  Rather disappointed because I have quite a few 1080ti's I had planned to put in these cases but they are too long.     I do have some cards that will fit but going to have to figure something else out for my largest 1080 ti's

right now I'm just 'burning it in' with 2x 1080tis and a 1050ti installed.   The 1080tis are crammed up next to each other so I could see if there were heat issues.  So far, none - at 65% power the hottest card is 64c.  we'll see how it goes with all slots filled and in summer time
