пообщался тут с разработчиками разными...
Пром.корпуса купить не получится - одни россиянские фирмачи не работают с частными лицами, вторые работают только оптом, третьи - только по гос.заказу.
Разрабы NatAmi пишут что готовый корпус б/у приспособить тоже вряд ли удастся - надо заниматься реверс-инжинирингом видеочасти экрана. (а так да - удобно было бы купить за 7 тыр Панасоник старый стандарта MIL-810, раздербанить и вставить плату ??? )
Порекомендовали самый реальный выход:
If you want it ruggedized, get an aluminum-suitcase styled mini photography case, or small cosmetologist's makeup case. You could, alternatively, get a musician's "Anvil" case. Find a cheap source.
Measure the top half of the hinged case, diagonally. Next, find an appropriately sized lcd displaythat has standard svga signals on a hd15 connector, and can run off of a DC power source.
There are sources for this gear, you just have to look.
Next, find a 3/4 or 1/2 sized USB keyboard, that fits snuggly in the lower hinged portion of your case. Next get a USB trackball that the system will see as a mouse. Create a panel housing surround for the keyboard, trackball & LCD display out of plexigass, polycarbonate, or sheet metal. A drill, T-Square, pencil, & a HACKsaw go a long way.
This will give you a polished looking ruggedized case with keyboard. You will have about 3.5" of depth to work with below the keyboard for an array of rechargeable batteries, and an equal amount in the upper half, behind the display, for the motherboard of your choosing. (this way is better, since the batteries are heavier, and will keep the case more stable in use).
You can get a short ribbon cable and wire your hd15 cable with it, so that it fits nicely. Cut grey a PVC tube into thirds, to make perfectly complementing molding for the aluminum case. 2 part epoxy holds anything on, permanently. Drill a hole behind the lower hinge, and mount a jack for your rechargeable battery array. You may want a power supply for plugged in AC use, but it will make the system a lot heavier. I would suggest making it as a module which can be removed easilly, by say, lifing out the keyboard.
You will want to have a meter or gauge that shows the strength of your batteries, since there is no 'power management' you risk the system shutting off, in use. A simple radio shack battery tester can be disassembled & integrated for this purpose, or you can get more technical, and do it the right way. lol... but it will require much more effort.
Be sure to canabalize the stuff that you get... you don't need the plastic housings, only the actual components. Make your own housings. Make it as light as possible. Then make it lighter. You can pattern-drill the alluminum case for ventilation, and to reduce weight (like cross-drilled brake rotors for cars)... just use a t-square, pencil, and a drill.
A few other odds & ends, but that's the basics of it. Sheesh, never say that there is only ONE way to do something. lol. Happy hunting.
