Ahhh yes of course the chinese ones you can get very cheap in fact if you go on ebay you can find them for even cheaper around 5-10 dollars. I've never looked inside them so I can't say anything about them. Another thing that seperates us is the smaller form factor as these are rather tiny. Also these will be opensource. And yes most likely heatsinks will have to be added...not sure if it should be extra or not I will probably just throw them in.
