Maybe if you drop the soundcard you can use the money toward a better CPU.
The MB and PSU are not great, but they'll do the job.
I'd pick the PC-7B, but the NZXT Hush is nice too. Both are $90 at newegg right now, both have two 120mm fans, etc.
+1 for the 9600GT, it is indeed better than the HD 3850. If you have the option to pay some extra and get a HD 4850 do it.
