Use a i7, from expereince of others, Intel just seems to perform better than AMD. Although its your choice. (i7 have a large overclocking community as well). I would also get 6GB of DDR3 memory, a XP SP2 64 (or 32) Bit and Vista 64 (or 32). Just have one OS running 32 incase of a uncompatibility issue. (I heard XP x64 has compat issues so I just use a x32 dual booting with a Vista 64.) And maybe a low power integrated G-card becuz NVidia supports switching graphics card to eco-mode if power bills are an issue XD.
You Might want to switch out the HDDs for one SSD (For boot sector and resource heavy programs) and 2 250GB - 500GB HDD so in case one fails, you have another one for back up.
