Help with diy project, connecting laptop screen to my desktop

[songorocosongo]

My laptop stopped working 6 months ago and the warranty had already vanished. A technician told me the problem was the motherboard so I took the HDD out and now I'm using it as a secondary drive(he didn't charge anything). Since I saw no use in the laptop I opened it to see what part I could use to make anything. I found the wireless adapter, the RAM, the dvd drive for a future laptop and finally the screen. After doing some research all over the internet I found that it's possible to use it dor my desktop with a LCD controller board. I found the controller board at ebay

But I need a source of power for the board and I don't wanna use the laptop battery charger all the time. (I will if there's no option)
Where can I find a cable that is in one side 12v 4A (hp laptop type) and on the other side anything that could work with my Corsair CX600? 6-pin PCI or one the ones used for the fans?

Additional details:
Lapto was a HP G42
Screen resolution 1366 x 768

Also if you know an easier way to do this I accept any suggestion

You're going to have to make your own by splicing the connectors together, and you absolutely DON'T want to use your case PSU unless the display.is going to be in or part of your case where the wires/connections are contained.

If you want to use it OUTSIDE the case you could use a round connector like a laptop, drill a whole in the back of your case for it, then connect it to your PSU via a molex on the inside, and a separate, unpluggable cable to the LCD.controller board.using a round connections on both ends. That way you can also use the laptop supply directly to the "display".

None of this is difficult if you know how to solder and anything about electricity. Radio shack has the parts. I would highly suggest using an in-line fuse between the molex and LCD controller either way if you insist on powering it off the PC PSU.

BUT using the laptop brick is a MUCH better idea and keeps you from damaging your PC while you're fooling around, and prevents you from hurting yourself if you DON'T know what you're doing.

But why not thinking about this one http://www.ebay.com/itm/M-NT68676-2A-HDMI-DVI-VGA-Audio-LCD-LED-Screen-Controller-Board-Diy-Monitor-Kit-/110977522562?pt=US_Server_Boards&hash=item19d6c69b82 , it is with HDMI input/DVI input/VGA input Option. I think it is more popular . Isn't it?
