The main problem was getting a driver for the LCD panel, I found this one M.NT68676.2A which I was able to buy and have programmed for my LCD by a company on Ebay and cost about £25 including a button board and custom cable for the LCD.
I also wanted to be able to run my Pi-Portable from almost any DC power source, car battery, laptop power supply, laptop battery...; the LCD board needs 12v, but will run happily down to 7v and the Pi 5v. Luckily the LCD board provides a very stable 5v output, which on testing was able to power a Pi, hard disk and USB hub, with WiFi and Bluetooth dongles plugged in. So all I had to do was power the LCD board; I did this with a variable voltage switching regulator, it'll take any DC input from 11v to 40v and output 9v which I use to power the LCD, the LCD board then powers everything else.
The top of the base box is steel, re-purposed from a video recorder metal top, the bottom tray is sheet aluminium. I needed the top to be strong as the lap top hinges were going to be bolted to it, and they are quite stiff to allow the screen to be angled.
Because I knew the base unit box would not be heavy enough to be hinged like a laptop, I had to turn the hinges around, so that they hinged the other way to normal, this was a real bugger, but I eventually managed to get it reasonable, it won't quite fold flat, but is good enough for me.

I obviously had to fold, drill and file the base unit to accommodate all the bits. Folding was done with just a vice and a thick steel edge like a chunky steel ruler and pliers/mole grips, and G clamps. All holes were drilled and then filed to the appropriate shape for whatever was going through them.
All the components are bolted to the base with nice small headed screws and bolts, there are a scattering of stick on felt pads as feet.
Almost as an after thought I realised the lap top had a pair of mini speakers, so I was able to wire them to the audio amplifier built into the LCD driver board, I can also plug in a pair of head phones, or better speakers to the rear panel, which automatically cut out the built in speakers. So with audio over HDMI I also have sound.

The keyboard & mouse are now wireless, using a wireless USB dongle, I'm using Noobs to dual boot Raspbian and Risc OS, and this keyboard & mouse works perfectly wit this.

Hope this is a bit of inspiration to someone.
