Just got back from setting up my 12 Baby Jets. I have Scrypt rigs running in the back. 95Mh/s. I got tired of waiting for HashFast.

HashFash really needs some more Quality Control..
I'm not talking about Major problems. Of the 12, I only have 1 having problems.
But a lot of minor stuff:
Random screws loose and rattling in the case
Random Case parts (i think HDD bays) loose and rattling in the case
1/4th of the BJ's had the fans from the Radiator set the wrong way. Or 3/4th, depends how you look at it. 1/4th were pulling air down into the case. Only 1 fan in the back of the case was exhaust.
Random SD cards! I swear, there were like 3 different brands. I'm not sure, think all were 8GB.
That's about it. I'm sure it wouldn't be hard to get these right. A loose screw in the case could short the board or fall into the radiator.
