Micro Center and many others have P67 Revision B3 available. I took my recalled P8P67 Pro back today and got a full refund, but they had several P67 Rev. B3 boards in stock.
I doubt you will find many people in an overclocking forum who select a board that does not overclock! Hopefully, there is one though and you can get your answer.
And I realize that the H67 does not overclock... but so far with mini-itx systems you gotta take what you can get .
