Ultra low power PC

[ir_efrem]

I am trying to find parts for a very low power PC.

I saw a motherboard not to long ago with an Intel Atom, 2 SO-DIMM DDR2 slots, a single 12v power connector for a *brick style" power supply (looks like a laptop PSU), and a single hard drive power connector on the motherboard.

I would like to find another motherboard just like this but I am having trouble locating such a beast.

Requirements would be:
SO-DIMM DDR2 (2 slots preferred, 1 slot is ok as well)
Single power connector (no 20 or 24 pin PSU connector)
CPU type does not excite me, though I do not want a desktop or mobile Core2. Atom or equivilant would be greatly preferred.
DVI would be a huge bonus but is not required.
Would be nice to see a power connector onboard for the hard drive.

This will be running Linux/Open Office/Mozilla
Target uses will be Document Creation and webmail - I don't need tons of CPU power and I do not need wireless.

I would appreciate it if some one could point me in the right direction because I am getting tired of looking at pages and pages of ITX parts without finding what I am looking for.

Thanks

Arent desktop Atom's here or very close?
They would certainly be the most power efficient.

Anything mobile will be the way to go. "ULV" or "LV" branded chips are also good.

This is where you'd start looking!

The atom 230 is a single core, the 330 is dual core. The Celeron is going to give you exponentially more power than the atom for a few more watts.

If I were you, I wouldn't go with a laptop-style power brick because it will be hard to find a replacement if it dies. Go with a case with a standard TFX12v (I think) PSU. Better yet, find a case which includes a nice small PSU.

BTW, The VIA C3 is pointless unless you want your computer to be a router. It's strictly embedded device territory. (I think some cell phones are VIA C3 now...)

The C7 will give you power which is less than the Atom, but it is a little more energy efficient. The Atom (by far) has the best power/performance curve.

Depending on your needs, choose a 230 or 330.

I just found Intel D945GSEJT

Only 1 memory slot but it fits all of my other requirements quite well. Newegg does not sell what I am looking for. I did manage to find the right motherboard (after I asked the question)....

Funny how that works sometimes.

Oh and 12v power supplies are cheap and easy to find. I found several quite quickly, 48watt for about $19.
