Yeah, that power supply looks sweet. Larger fans are quieter, since they can move more air at lower rpm. If you use a small fan they have to spin fast and you get a high pitched whine.
That's really a monster power supply. That's the kind of power supply you need when you have an overclocked CPU, plus dual high powered video card in SLI, plus a bunch of hard drives, optical drives, etc. I'm sure it would be more than adequate for your needs, if not overkill. :)
If you want very high quality power supply, that one seems to be fine for a reasonable price. If you want to save some money, there are other options out. there.

If figure you could buy both those cheap power supplies for the same price as the one you posted even before getting the rebates back, and if one doesn't work out you would still have a backup.
Plus you could save some money to put towards other components.
