Not sure why you compare a PC to a usb hub, sure you could get a cheap PC for the price of a usb hub, but you are still left with about 2-3 USB ports and if you plan on running 3 miners on a PC you most likely won’t be able to fit them side-by-side or have enough power to keep three running on a cheap PC.
This one looks good, it can provide max 2.1A per port, so 4 sticks+Rpi+fan should go. I'll think about it (and will try to find it closer to me due to post/taxes). No, I don't intend to use PCs or laptops instead of hubs, I just compare prices because I can't imagine whats inside hub for $150. I know whats inside $200 laptop. Hub should be bunch of wires, some kind of trafo/regulator, usb ports and housing. I just hope in my poor knowlage somebody is having fun...
Now, on topic. Do you or anybody knows how to get some kind of bfgminer history? I can see on my terminal screen whats been happening last 5 minutes, accepted shares and all, but I want to look before. I want to know what happend during night, what kind of errors I had and so... Is there any file with those data and how to approach it...? I am on Linux.
