But this isn't a typical "modern" x86 CPU.  It's one of VIAs Eden or C3 
cpus, power consumption figures quoted below, but figure that some of them 
are designed to run with no heat sink on the CPU.....

<from the Mini-ITX FAQ>

1.6. What is the Eden architecture?

    The Eden range of CPU's especially tailored to low power applications. 
The CPU outputs very little heat, and only passive cooling is required under 
most circumstances. There are currently 3 models of Eden CPU:

        * Eden ESP 4000 400Mhz , 100 MHz FSB (x4 muliplier), 128 KByte 
Level-1- and 64-KByte-Level-2-Cache, 1.05 Volt, 1.7Watts
        * Eden ESP 5000 533MHz, 133 MHz FSB (x4 muliplier), 128 KByte 
Level-1- and 64-KByte-Level-2-Cache, 1.20 Volt, 2.8Watts
        * Eden ESP 6000 666MHz, 133 MHz FSB (x5 muliplier), 128 KByte 
Level-1- and 64-KByte-Level-2-Cache, 1.20 Volt, 2.8Watts

Compare the ratings above with recent Athlon CPU's that consume 70Watts!

1.8. What is the C3 architecture?

    The C3 range of processors can share the same EBGA physical design as 
the Eden but are considerably more powerful, fairly similar or faster than 
Celeron processors of the same clock speed, but consuming less power. There 
are many models of C3 CPU:

        * C3 700Mhz (7.0 x 100-MHz bus) VIA C3 Samuel 2, 5.81Watts Typical, 
9.88Watts max
        * C3 733Mhz (5.5 x 133-MHz bus) VIA C3 Samuel 2, 6.09Watts Typical, 
10.35Watts max
        * C3 750Mhz (7.5 x 100-MHz bus) VIA C3 Samuel 2, 6.23Watts Typical, 
10.59Watts max
        * C3 800Mhz (6.0 x 133-MHz bus) VIA C3 Samuel 2, 6.65Watts Typical, 
11.30Watts max
        * C3 800Mhz (8.0 x 100-MHz bus) VIA C3 Samuel 2, 6.65Watts Typical, 
9.88Watts max
        * C3 800Mhz (6.0 x 133-MHz bus) VIA C3 Ezra, 5Watts Typical, 
8.5Watts max
        * C3 800Mhz (8.0 x 100-MHz bus) VIA C3 Ezra, 5Watts Typical, 
8.5Watts max
        * C3 850Mhz (8.5 x 100-MHz bus) VIA C3 Ezra, 5.5Watts Typical, 
9.3Watts max
        * C3 866Mhz (6.5 x 133-MHz bus) VIA C3 Ezra, 5.6Watts Typical, 
9.6Watts max
        * C3 800Mhz (6.0 x 133-MHz bus) VIA C3 Ezra-T, x.xWatts Typical, 
8.5Watts max
        * C3 866Mhz (6.5 x 133-MHz bus) VIA C3 Ezra-T, x.xWatts Typical, 
9.6Watts max
        * C3 933Mhz (7.0 x 133-MHz bus) VIA C3 Ezra-T, x.xWatts Typical, 
x.xWatts max
