February 2022 Update, mainly for the Redditors who've since found my build: Soon after building it, I upgraded this thing to having a Core 2 Extreme x9100 and a 2GB Radeon R9 270X, as well as upping the hard drive to a far-better 500GB Seagate SSHD. I also ripped out that metal netting on the video board's housing, and swapped it for two of those round wire fan guards, like you often see on towers. I never got to upgrading the RAM, though it was something I had wanted to do. I built this thing in 2016/2017, out of a laptop I'd already had for five or so years from new.

I made my own gaming laptop with the EXP GDC Beast. I fitted it to the lid of the laptop ond made it work with the built-in screen. Here it is:

Setup insights
- Samsung P510 (also called the R510; both are fully the same)
- 1280*800 screen (Samsung LTN154AT09)
- 4GB DDR2 mind
- Intel 4500MHD built-in video
- Intel Pentium T3400 main chip @ 2.17GHZ
- Windows 7

Outside video board hardware
- EXP GDC Beast video board slot, plugged into the ExpressCard slot
- Sapphire Radeon HD 5750 with 1GB of video mind
- Screen input board, for showing it on the built-in screen, wired to the laptop's feed through a step-down switcher
- Screen backlight wired to always stay on as long as the screen input board is switched on
- Plug/header setup for switching between the built-in video ond outside video board
- Homemade housings for everything, all fitted to the laptop

Hardware shots (you need to have five or more write-ups already for the upload switch to show. Otherwise, you can link them from any other webside.)
See below.

Installing steps
To get the video board itself running, I did not have to do anything great. Only plug it all in ond install the drivers. It has to be clicked into the laptop once the BIOS has already gone through; the built-in lag timer lasts not long enough to do this on its own. I had to make a lot of wiring to get everything else working - to find out how I wired all else up, read the full write-up umbe this setup below.

I haven't any of these, but you can see some shots of it running games on the full write-up below.

Other thoughts
I like this setup for that it is all in one clump; that is, I have not lots of bits spread out on my table to have this up ond working. It is all in one, fitted to the back of the laptop, so it is a homemade gaming laptop that is onefold to take out of the house wherever I go. If I wish to brook the stronger, outside video board, I can plug it in ond link the screen to the "OUTSIDE VIDEO BOARD" header. If I want to brook the weaker, built-in video chip (such as for going into the BIOS), then I can plug it into the "BUILT-IN VIDEO" header.

You can read more on it by my webside, although I wrote that a few years since, so it shows the laptop in its earlier days.
Thank you well

Here are some more shots of the laptop:

"BUILT-IN VIDEO" , "OUTSIDE VIDEO BOARD" - this is for choosing if either the built-in video or the better, outside one, is shown on the screen.

(Running GTA IV)

(Running Race Driver GRID)

(Running GRID Autosport)

(Running Heaven)

(Running Colin McRae Rally 3)

- (Samsung P510 laptop)
- Intel Pentium T3400 @ 2.16GHz
- 4GB of 800MHz DDR2 mind (<"RAM")
- Motherboard with 478-pin Socket P slot
- Sapphire Radeon HD 5750 1GB video board, overclocked to the speeds of an HD 5770
- Realtek HD Audio
- Hitachi 160GB hard drive ("SATA")
- Sony DVD writer, inside 
- EXP GDC Beast
- Screen input board for Samsung LTN154AT09 screen (with the backlight feed board)
- Step-down switcher for the screen input board (with its own small screen to show the output readings)

I shall be stepping up the main chip, in the forthcoming, to something higher end. I have not yet chosen what. Maybe a Core 2 Extreme, ond maybe even a four-hearted one if it will work with it (so in other words, a Core 2 Quad Extreme). The chipset is an Intel GM45, so it should work with one. 

To make that setup for switching between the built-in video ond the outside video board, I had to cut the screen plug from the laptop's built-in screen wire, ond wire some header pins into its stead. These header pins have the same pinout as the ones on the screen input board. I then got two header lengthening wires (both the same kind) ond plugged one onto this new header that I had made, ond the other onto the header of the screen input board. I ran these wires to the outside of the housing, so that both of their headers could be reached from the outside. I then plugged the screen wire that comes with the screen input board into the back of the screen, ond ran its other end to the outside of the housing (to where I had put the two headers). I plug this into whichever header I need at a given time; either the one for the built-in video's output, or the outside video board's output. I marked each header with the right name - "BUILT-IN VIDEO" ond "OUTSIDE VIDEO BOARD".

The backlight of the screen has to be on whenever the screen input board is switched on, so that it does not darken whilst it is linked to the built-in video of the laptop. The pitfall here was that the backlight would only come on as long as there was an input found on the screen board (such as a live VGA wire plugged in), therefore it would darken after a few seconds when running on the built-in video. My answer to this was to first wire the two pins for the on light together - the red one (which lights when there is not an input), ond the green one (which lights when there is an input) - ond then to wire this new mix to the backlight-on pin. That way, the backlight is always on when the screen board is on, for that there is always a 3 Volt input found at the BL-ON pin! 

I have made housings for everything as well, so that nothing shall be shorted out. The step-down switcher came with its own housing for me to put together. Once the Volting was set up on the step-down switcher, I took out the knobs from its housing, ond put screws into their steads. This was so that the switches would never be bumped into, mistakenly setting the Volting too high ond breaking the screen input board.

One thing that I do not like with this setup, is that when I have switched the laptop on, I have to wait for a bit before clicking the outside video board into the laptop's ExpressCard slot. The lag timer which is built-in lasts not long enough for this laptop, even on its longest setting. There is some good news though: I have thought up an answer for it! I will make another write-up some time later for that. Smile

Thank you well again for looking.

You can play some actually game? example GTA V, of course with RAM improvement!

Yea, it can run games fairly well - much better than before it had the outside video board. I have not GTA V, so I have never played that on it. But it should bear to run it.
