New computer - Case and PSU

[capsad]

Hi,
I want to buy me a new PC with following hardware:
CPU: QX9770
Board: Asus Formula Rampage (X48)
PSU: 750W Amacrox FreeStyle
GPU: I take a cheap one and wait until the 4870XT or GT280 will be released
RAM: 8GB, Mushkin, XP 8500
CPU fan: Noctua NH-U12P (with 2 fans in push-pull)
hard disk: 1x veloci reptor, 2xsamsung (still have to choose) in raid 0

First question: Is the PSU enough?
Second: I'm still looking for a case, at the moment I think I will take either the Coolermaster Cosmos RC 1000 or the Coolermarster Stacker RC-832. As far as I know, the Stacker is not that silent. Can anybody give me some advise? Do you think the Stacker will be too loud? Or will the computer be cold enough if I take the Cosmos?
thanks in advance for your help,
bye

That PSU is more than enough. In fact, you could probably loop it back into your house's electrical meter and sell some of that juice back to your Power Company.

From what I've heard the Cosmos has poor cooling. Also look at Antec, Thermaltake, and Lian Li cases which are also good.
