This may help a few of you out there not wanting to build your own computer and What I did to avoid it.....
I went with a LG 23" LED backlit Monitor flush mounted into the nav station. it has a nice ridge around the outside that allows for flush mounting and only sticks out about 1/16th of an inch. the whole monitor is not much more than an inch thick Runs on Straight 12 volts.... No issues yet. Draws 2 amps off the battery
. (bought at Sams Club) same screen a previous poster referenced here Red Sky at Night » Low Power Computing Update
true USB MARINE GPS Antenna Amazon.com: Rose Point Fixed-Mount Marine USB GPS Sensor with WAAS: Sports & Outdoors
but any would work, just need the signal!
The computer is a Asus EEE PC. There are several models. I went with the most powerful for about $400. They run on 19vdc. (they now have a more powerful one for about $550) also WIFI is buit in. i got internet
on the boat. I also tether my droid phone
in for internet
on the go and coastal cruising

The easy voltage conversion was to buy the following
BYTECC 100 Watt Converter, NOT INVERTER
This little guy is $29 and takes your 12vdc to 19vdc or any other low voltage for the computer it has selector switches on it for different voltage outputs. Probably close to 100% efficient.

The other cool thing about it is it is AUTO SWITCHING, so I hard wired the 12 volt side to the dc panel and it also has AC voltage that I also hardwired in. If I am plugged into shore power
, the whole system runs on AC AUTOMATICALLY, no need to think about the batteries, and for $29 you can't go wrong.
Note the above setup is for inside the boat at the nav station, the Cockpit
view is provided buy a USB powered monitor that is 9". the monitor runs totally on USB, for power and video, It's great. I have it mounted to the inside of the boat with a hole cutout to the cockpit with glass covering it, (out of the elements but viewable.

I know alot of you are running OPENCPN
. It is nice but for my setup with multiple monitors I am running PolarView, its $40 for a license
and well worth it for me. The layouts and speed are incredible with this PC. I also run their free Polar Com. It alows you to setup gadge screens with nema data. A great app for setting up my wind
/ SOG / any other available NMEA
stuff on either screen for viewing. try it here for 30 days (no affiliation) Polar Navy - Marine Navigation Software
data was a little tricky for me since I have some older Raytheon wind
ST60 gauges on Sea Talk. I had to buy a Multiplexor from here NMEA Multiplexer with optional Seatalk-NMEA bridge + USB.
to make it all work easily and output all this data to my autopilot
to steer by wind and heading all from PolarView. Overall I am VERY HAPPY, and would not change a thing. With all the hardware
running it draws about 4amps, Sorry for the lenghty post, but I have reaserched all this stuff for years and finally did it!
