    It's still cheaper to use industrial off-the-shelf x86 boards than custom x86 boards.

    Why more components? Intel offers multicore x86(-64) SoCs with 8 PCIe lanes, USB, SATA and GbE for 60 USD. That's about the same feature set as PPC SoCs (ignoring PPC's DIU, which isn't suited for real desktop use anyway). And Intel also offers multicore x86(-64) SoCs with 4 PCIe lanes, USB, SATA and 3D GPU for mere 30 USD. Here you'd only need a cheap separate Ethernet chip. Audio would be needed separately with all those solutions, including PPC SoCs.
    From AMD you can get multicore x86(-64) SoCs with 8 PCIe lanes, USB, SATA, GbE (using one PCIe lane), HD audio and 3D GPU for 70 USD. That's really all-in-one.

    Well, 30 USD for an Intel x86 SoC with 3D GPU (only lacking Ethernet compared to PPC) or 70 USD for an AMD x86 SoC with really everything needed. I think this would come out cheaper than PPC.
