that nforce 4 ultra xpc i linked you earlier doenst include a pci slot. it will be pci-e 1x. the integrated audio it's using will be the envy24, which its quality rivals that of the audigy 2! as for the poll and such, tho i like the G5 model better, its 240W psu wont be enuff to power dual-core, which is what i'm looking forward to. the P serie's 350W can easily support it. knowing that the shuttle 240W can handle an fx-55, x800 xt pe, a sound card, 2 raptor hard drives, an optical drive, and etc, an additional 110W can easily support dual-core.
