I'm going 64 bit by the end of the month. I'm getting the 3400+ and the Asus VIA motherboard. I'm also switching to Swiftech liquid cooling which I'm going to cool my mobo and GPU with at the same time. I'm also upgrading my case to the Thermaltake full server case, it should be in Thursday. I'm getting 1 GB of the new Corsair Ram that is TwinX and has the new coolers with the LEDs on them. DDR400!
