Hi Deiske, welcome to GeeksToGo!
I have looked at your build and it looks great. However there are a few things I would change:
PSU is the most important thing in my opinion as it powers all of your components and if it dies, there's a big chance that it will take the other components with it. You want quality so don't cheap out on this one. So for my suggestion, this Antec Sonata III would be the only Case/PSU combo I'd recommend. It is quite expensive however Antec makes great cases and power supplies. You can also split it up and get something like this Antec 300
+ PC Power & Cooling 500
W = $49.95 + $69.99 (with a $20 Mail-in-Rebate) = $119.94. You can trust the power supplies from Corsair, PC Power & Cooling, Antec, Seasonic, Silverstone.
For the RAM, the one you picked is okay but if you take advantage of the Rebate, this Corsair RAM
is a bit cheaper.
For the harddrive, Seagate also has a 500GB drive
that costs cheaper than the one you picked. Seagate also has 5 years warranty than Western Digital's 3 years.
For the video card, a 9800 GTX from BFG Tech costs the same as the PNY 9800GT you selected. Also, BFG offers limited lifetime warranty (does not cover modding) and the GTX performs better than the 9800GT. However, the GTX does not come with a game.
Last thing, the on-board sound is pretty good so I would only recommend getting a sound card if you're an audiophile. Maybe purchase it after you've tried on-board? See how on-board perform first so you don't waste your money on something you might not even need.
Hope that helps.
