wow someone did their research!!
i really cant see anything wrong BUT u could get a neopower 480W psu for the same price, and its better, u mite need a different heatsink if ur planning on OCing t a lot, but other than that, thats a very good system
the neopower is worse then the HE series from antec, the HE serise come with 3 +12V while the neopower only comes with 2
the zalman heatsink is good, make sure you get some AS5(artic silver 5)
i would get some better ram with better timings but thats just me. actually i would go with 2GB sense thats the new thing. and thats the new 1GB for the gamign rigs
