-Get 2X1GB of G.Skill DDR500 ram. With rated ddr500, you can overclock, and have stock speeds. So if you want to, you got it...
-Best get a 7800gt instead of a x1800xl. Unless you get a REALLY good deal.
-Get an Opteron 170 that's on sale in the hot deals thread for $351 right now. Dual core + overclocking crazy. Socket 939.
-Asus Vento isn't really a good case, but if you like it, get it. Otherwise I'd steer elsewhere.

For power supply. these choices.
-Enermax Liberty 500w
-Antec NeoHE 500w
-Seasonic S12 500w
