I have been researching different tower coolers for a new build. I have been looking at the following CPU tower heatsinks,

I am looking at the Nvidia 8800 video card or the ATI 2900XT 1 gig video cards.

I am not sure of which motherboard to get because of the size of these coolers and what case and PSU to buy. I have read many reviews of the antec 900, the antec P190, 182, 182B, Thermaltake armor sieries and I am just confused at what has the best cooling performance. Some sites recommend 9 bladed fans because they move air better or to look for fans that the blades have a certain aingle pitch.

My goal is a very cool (tempature) case with a side fan, cpu, PSU, and vidio card(s). I have some reservations about the DX10 hardware because I read an article microsoft went from DX10 to DX10.1 because they screwed up with DX10 and that the hardware would need to be DX10.1 compliant.( I am not sure if this is solved by a firmware upgrade or not).

any help on this to keep things nice and chilly inside a case and a good power supply to power all the components. I will use it for lan gaming, school, the internet, video encoding, ect... any help, advice and suggestions are welcome. I have a few weeks left until school starts for my wife so I have probably 3 - 4 weeks until I have to buy for home use and school.

Thanks!
