Got 30 Blades on three motherboards at one location. Commercial off the shelf fans cooling them down. I laptop used for proxy server.
At home 4 original blades at 13 GH/s and one V2 at 10.
10 USB erupters from when they were selling for $6 on eBay.
Someone gave me 10 bitcoins once for fixing his computer. I sold 7 of them for $207. I'm still kicking myself for doing that.
At least I've used the money to buy a new stove for my house

Wifey is happy.
