I got my miner today.
It's one of the black ones with 4 fans that sounds like an old 707

It's loaded with dust on the fans and blades...obviously "well tested", but it hashes at 960GH/s and it cost me $1500 delivered, so yeah, that's OK with me.
The only problem I had was not being able to find the ip on my network, so I reflashed the SD and that did it.
