Actually aside from not having a direct P4 CPU power connector (easily solved with a molex to P4 adapter or a little soldering) the M1 is superior to the M2 because of its higher output on the 5v rail (10A on the M1 vs 8A on the M2). Both the LF and LF2 are very power intensive on the 5v rail and use between 3.5 and 4A of 5V power. The 5V draw for a standard notebook hard drive is 1A and a notebook DVD drive is 1.5A, leaving you with just 1.5A before you are maxing the PSU out on the 5V rail. It should go without saying it but maxing anything out on a PSU is not ideal and will reduce the life span of the PSU.
Yeah, but the M1 is only good for 2A on the 12V rail. Fail.
What do you need 12v power for on the LF board? It uses next to no power on the 12v rail! I would still rather have extra power for 5v USB devices then useless 12v power that is not used. But that is just my 2 cents.
Lilliput screens are said to use around 10W, dunno if that is for the LCD or CCFL version but 10W is near an amp of 12V. The Atom processor itself has to draw something from 12V, otherwise they wouldn't have the P4 connector. If it draws the whole 8W TDP off 12V, that is max of another ~2/3 amp. I have an XM receiver which also draws power off the 12V.
What would be really sweet is an easy way to add another linear regulator to the system to convert some of the excess 12V from something like the M2-ATX to 5V.
I use a video capture card on slot 1 and a wireless card on 2
I've got this board, its still in the desk build stages (meaning I haven't ran it with my m2-atx yet) but so far it looks great, way better than my m10000.
