Good choice on the Q6600, in love with it at the very moment ^-^. Also, CORSAIR and the Antec PSU are fine choices as well. CORSAIR makes fine PSU's aswell, loving my 750TX, but it is around 109 I believe :\, but Antec PSUs are fine, use them for cheap builds for the family ^-^, have not had one fail. As for the Mobo, I really do not trust any brand other than ASUS or EVGA for motherboard :\, but that is just me.
