This is a great mining rigs which you have made. I completely admire your efforts and I can say that you are doing a very good job creating such a good hardware. It will be great if you can share the methods how to make these hardware and where do you buy such hardware from?
Thank you

! I got the the Antminer S1 local from a Guy who sells them in bulk so I might buy 10more from him soon

my 4 600w psus are from a site called "webhallen" and my friend found the 5th psu in his basement

the "thoughpower" is also locally bought, they run very well

I don't recommend buying the cheap 600w for 25euro, I did that once and they blew up.
I'm thinking of buying the S1 upgrade kit either local or from EBay soon.
