So what do you think????

I'd go with the Sonata III, which has a 500 watt Antec Earthwatts.

It's not just a step up in wattage, it's a much better psu than the Antec SmartPower 2.0.
 
The best Antec PSU's are the Earthwatts, the Neo's and the TPQ's.
 
I have the Antec Nine Hundred:

It doesn't come with a psu, so I got the Antec Neo 650 for the 6+2 pin connector for my MSI overclocked 3870x2. That was $99 at Newegg.
 
If you like the Nine Hundred, you could get it with the Earthwatts separate. Don't skimp on the PSU, at least get the Sonata III.

Agree, if you're getting a new case, get the Sonata III.  Have a couple of Sonata IIs that have been very good but the III has a better PSU.
