Everything looks good, but I would recommend an Intel 510 120 GB SSD because you'll be using this as a primary drive and the Intel series are the most reliable SSD's on the market.

If you're looking to cut costs you don't need a 850 W PSU. The Corsair TX650 would be enough for what you want and you don't need that expensive of a MOBO. An Asus P8Z68-V Pro would be more than enough.

As for the cooler, are you set on liquid cooling? If not, you can get the same or better cooling for less expensive coolers. The Hyper 212+ is $30 and is amazing, but if you want even lower temps you could get the Noctua NH-D14 for ~$80 which will outperform the H100.

Sound card isn't needed.

I can play Skyrim on near max with my GTX 460. You'll be able to fully max it without a problem with that system.

You should also reuse your old hard drive for data until prices drop. OS and games on the SSD.
