I have 232 x GPU's.  58 x EVGA 1080 Ti FTW3 and 12 x EVGA 1070 Ti.  All the rest are AMD RX 480's and R9 Fury's.  I'm going to sell all of them over the next 30 to 40 days.  I'll hold onto the motherboards, power supplies, power distribution units, CPU's, RAM and SSD's for "possible" future use.  I may sell all the other stuff as well and focus entirely on trading and my future trading/education website.

Scroll down here on page 6 of this thread to see my remodeled mining room.  Page 8 shows you what I have done for cooling with 36 box fans:  https://bitcointalk.org/index.php?topic=2865914.100
