(this company claims under 1 W ??). I've seen comparable ones that run ~15 W
advertised.
Where should I look for this kind of PC ?
Let's be clear on this - Are you looking for a "PC" (implying, Intel
x86-compatible), or a single-board computer, processor=don't care as
long as there is a Linux port? The link you posted is to an ARM-based
SBC.
If that's what you're looking for, you might want to look at Bitsy

products, and similar devices such as the Cerfboard

If power consumption is your major issue, then RISC solutions are
really the only way to proceed. However you do need to define your
requirements a little more strictly; "133MHz" processor can cover a
wide range of performance depending on the architecture of the
processor and the board into which it's integrated. Some idea of the
target application would help narrow this down.
If you need an Intel-compatible (PC-compatible) board, then perhaps
you can look at solutions based on Geode (200~333MHz), or ST's STPC
series (wide speed range from ~50MHz upwards). There are also a few
boards based on the SiS 550 embedded x86 SoC (200MHz). For these
products, look at vendors like Advantech (
www.advantech.com) and BCM
(
www.bcmcom.com). Support is much better from Advantech, prices are
[generally] slightly better from BCM.
These are all much greedier than your 1W requirement, though - more
like 9-10W minimum for a complete system. The Via Epia series of
motherboards, recommended by another poster, are *way* outside your
power budget; the slowest of them requires about 4A on the 3.3V rail,
1.25A on the 5V rail, and 300mA on the 12V rail, with peak current
requirements being considerably greater than that. They don't publish
useful numbers, because they intend you to run the board off a
standard PC power supply, so those values are actual measurements I've
taken when trying to work out a power budget for the Epias.
