Wow they are some serious gpu rigs! These pictures bring my happy memories of gpu mining flooding back 
!
They are quite fun, it is a lot more hobbyist that just buying antminer and plugging an ethernet cable. They can be a lot easier to screw up too that's for sure (DAMN YOU ESD!)!Ha ha yes I agree, getting them set up and running properly was a nightmare sometimes but very rewarding when everything was working
