Thanks and I'm close to ordering the motherboard and it will use the same chip set as the ASUS.................I may be doing something similar, using an ASUS eee 701 I bought 3 years ago. You might want to consider a computer in the "netbook" class because they're compact yet powerful, and many will power from 12v, with a peak power consumption of 20 W or so.......

and this power supply....

along with a 320 gig drive. I'm hoping the whole computer and monitor will come in under 30 watts and think it will. It will go in a case that is about 10 1/2 X 10 1/2 X 3 1/2....

I'll add all of that to the build as it happens. I'd considered just buying the computer, but I wanted a detached monitor so I could put it up by the companionway opening where we can see it in the cockpit. I will also be able to move it down into the cabin for computer use or to watch DVD's.
