I'm so confused by all the available options on case, psu, and cpu cooling fan. Can anybody give suggestions based on my configuration? Pls choose them from

Thanks a lot!!!

Out of the cases, I think the best choices are the CM Cosmos and Cosmos S. Sturdy cases with good cooling and plenty of room.

With the PSUs I think the only ones I would trust would be the Corsair 650TX and some of the Thermaltake Toughpowers. The Corsair would be my top choice.

I don't have much experience with the CPU coolers, so can't really say.

Thanks.
Thermaltake ToughPower 600W and Corsair 650TX and NZXT PP800, their prices are very similar on cyberpowerpc.com, which one do you recommend for my configuration? I think my system doesn't need a 800w psu right?
