The main reason why I haven't mined yet, even though I have access to free electric,
is because of the need to buy tons of hardware, because the only desktop system I have now is AGP and PCI based.
It would be great if I could just plug in something by USB and generate. Of course, that's not possible, the closest thing is http://arstechnica.com/old/content/2008/12/amds-xgh-external-gpus-may-soon-see-the-light-of-day.ars
I just wonder if there's another way to GPU compute without having to buy CPU, RAM, mainboard & PSU. The difference is that with these things it's not really profitable but without them it's worth it. Is there a VPS provider out there that's cheap that would allow me to put a nice GPU in their machine for example? Isn't there an appliance for GPU computation that isn't NVidia for example?
Let's stay on topic and not talk about profitability for the moment please.
