I am building a pc with an EVGA 680i A1 type motherboard and probably one of those upcoming 45nm processors in January. I was wondering what would be best to cool it with (I am planning to overclock a bit). Some of the cooling solutions I saw interfere a bit with the intricate heatsinks of the mobo, but I want something which will fit on that motherboard. I also want something pretty quiet, since my family will also be using this PC. Also, what sort of case should I buy to house all of this. I was looking at the Antec 900, Thermaltake Tsunami, Antec P190, among others. Which would be best, esp for a large, efficient and quiet heatsink? Thanks.
