An LCD Display for an Ultra-Portable Desktop?
dark_requiem asks: "I've just built a new system based on a Shuttle SN45GV2 XPC, and it's a great little system. However, I'd like to make it more portable by attaching a flip-up LCD display (preferably with speakers) to the top of the case. My video card has TV Out, so connecting via composite or s-video is no problem. The case is just under 8" wide, so the width of the LCD cannot greatly exceed this (it wouldn't fit in my carrying bag then). Thus far, I have been looking at the various 5.4" displays for console systems like the Gamecube, but all of these connect to the systems via proprietary connectors that stick out of the front of the displays and would interfere with mounting it to my case. Has anyone from Slashdot ever attempted a mod like this, or does anyone know of an LCD display that would suit this purpose well?"
I haven't looked at to many of them, but they are likely just using either: RGB out, S-Video or Composite from the system. You might just have to crack one open and see what they are using, you should be able to find pinouts for the video game systems. (And If it uses RGB, it is probably using it at 15.75 KHz) (My personal favorite for pinouts is GameSX.)
Take a look on eBay - you can generally find 7-8" LCD monitors for cars that take S-Video or RCA input. You can get them cheap, take a look: http://listings.ebay.com.au/aw/plistings/category1 4946/index.html?from=R11
(Note that that is an Australian URL).
I don't know where you are located, but around here, I would go to a high-end electronics dealer that dealt in in-car entertainment systems, the kind where the kids can watch TV in the back seat. You should be able to find a video-in LCD display from 5 to 10". Most will probably run off 12V power, but this is not that hard to get out of a PC PS.
Around here (Orange County, California) this would be Frys, Best Buy, or one of the independent auto shops. And if you mod me down because I said Frys, then I agree with your judgement.
LCDs for car installation usually have standard composite or RCA connectors on the back side so they can be flush with seatbacks or on the side for ceiling/dash installations.
Since you have a tv out, these two are about the right size.

Here's one, 7" 800x480 seems to be available all over the place (review).

7" widescreen touch screen, and it's only 250 bucks!
If someone says he and his monkey have nothing to hide, they almost certainly do.
Uh, what? You know you can get laptops with a 256MB Radeon 9800 card, right?
Were you wanting this to do actual work (coding and such), or just to play games? The answer will affect what screen and input type you need. Standard composite or s-video will not be enough (unless your screen is lower-res 640x480) to do any serious work with - but it would be ok for game playing (though icon text and the like will be difficult to read). Finally, if it hasn't been mentioned already, get in contact with these guys - they will be able to help you with your problems and needs.

I don't know if I'm a little late to post, but I think the best solution would be a 7.2" touch screen. You can buy these on eBay for under $300 (I hope money was not a concern in this project). They have VGA connections, hence a much sharper and higher resolution picture than anything you will get with S-Video or composite. I can tell you that running a PC off TV resolution is unbearable for anything but watching movies or music visualizers. They also have a nifty USB touch screen, great for when you have these things on the road, and you want to set it up without trying to get your mouse to work on your leg.
OK.
