Correct Klondike. And about the loss, it's no use crying over spilled milk.
The workers where not low paid. They got 3 to 4 times normal Thai salary.
sorry for your loss friend.
looking at the setup though... aside from your wiring setup (which looks far too condensed)... all you needed were spacers between the rigs and I think you'd have been OK...
I have 4 inches air gaps between each of my own rigs, after having 2 together and almost instant shutdown due to overheating.
