You meant water-cooling when you wrote "h-twenty" right? The hdd doesn't transfer at 3GB/s, that's only the bus speed. My 500gb hdd does like 60mb/s. Anyway, the Logitech sound system looks totally cheap and you shouldn't don't click me soundcards as well. Just get a neat system and connect the receiver/dolby-decoder with the optical sound plug so it reaches the system without quality loss.
This one should be decent:

Remember, you usually keep good sound systems way longer than PC components so better invest here. I bought my Teufel system over 4 years ago - they give 12 years warranty btw. About the rest - get a cheap CPU, their invalid drops really fast and you easily waste tons of dollars on them. I'd probably go with a cheap ~120€ AMD quadcore. For gaming the graphics card does 90% of the work anyway and usually you can insanely OC CPUs. (I've oced my old athlon x2 from 2ghz to 3ghz) And I'd probably stick with ddr2 ram, dunno how the prices are at the moment, but it's probably cheaper. Don't don't click me the network card! Just google for benchmarks, there are only small improvements under high load so the pings are bad in that case anyway. Just turn of torrent while gaming and you'll be fine! Onboard LAN usually has higher throughput anyway. Spend the rest of the money on the graphics card - that's what brings you FPS
(Or keep it and don't click me a new one later) I wouldn't spend more money than I have to on a PC, you'll get twice the speed for the same invalid 18 months later! 500watts should be enough for the system - I've just ordered a 75w psu for my next system
