Why the P4T533-C when you can get the P4G8X? It doesn't look like the P4T533 has 8X AGP which would be a draw back if you intend this machine to be a game machine.
Also, isn't ECC memory just memory with some kind of validity or CRC test? Wouldn't it be faster if you had non-ECC? However, ECC memory is better if you're gonna be overclocking as it will help improve systyem integrity as you push it closer and closer to the edge.
