Apart from the optical drive, you have pretty much everything.
Just a few suggestions though.
There is a higher quality unit available for less money, the PCP&C Silencer
is one of the best PSUs available. If you're dead set on modular, then the Corsair HX620
has the advantage over the Thermaltake Toughpower line, I think.
And will you be overclocking? You could save some money in places if you won't be.
EDIT: Don't buy the Zalman 9700, it's the most overpriced POS money can be wasted on, there are cheaper alternative that perform better. Xigmatek HDT-S1283

And great deal on the GTX 260 BTW, that's an excellent price.
