I have a bitaxe with 500GH/s and it does not require a PC or hard drive. you can configure it with a mobile phone. but you need a wireless network to connect the device to the internet.
my best difficulty missed finding a block by the factor of 1 million


Yay, then this one might be right for me. For helping the network, mainly. IDC if it finds a block or not.
Well, to be precise, i will care if it finds one, of course
