We’re a Top 100 Folding@HOME team! Take that Tom’s Hardware Community! No, seriously, we are that freakin‘ huge now. I celebrated by buying some more hardware to fold with. You can find out more at the Team Hack-A-Day Forum.  If you don’t know what this folding thing is all about, check the team wiki. You could always drop by our long standing IRC channel, #hackaday on EFnet.

Even though performance could not match that of manufactured heat pipes, it’s still impressive.
