We have let 6 cooling pots made to order (with sweet HWBOT.org engraving ). The top 3 submitters of the winning country get to choose one, than the top 2 submitters of the second country gets to choose one, and the best submitter of the third country gets what's left over.
We could say the winning country gets CPU pots, 2nd country gets GPU pots and 3rd country gets NB pots, but the fact is many people already have a CPU/GPU/NB pot, so we let them choose.
