Looks good to me. You may want to reconsider the motherboard, however. The A7V133, while being a very good board, cannot take full advantage of the CPU's capabilities. The CPU can sit on a very fast 266Mhz bus, but the motherboard only puts out 133Mhz max (you may be able to squeeze out a small gain via overclocking but it won't be anywhere near 266Mhz).
As you only need the machine for internet access, productivity applications, and the occassional game, the A7V133 is not a bad choice at all. If you see your gaming usage going up, you may want to consider the A7V266-E or the A7M266 from ASUS. Those boards will allow you to take full advantage of the CPU plus they will allow you to put much faster RAM in the machine.
