Hi people!

I know there are ways to hook up an external graphics card to an old laptop. However I do NOT want to tamper with the inside of my laptop. I simply want to be able to plug it in, download the drivers and move on. Thus I thought of a possible solution and was wondering if this was possible.

At home I have an old graphics card and an old power supply: A Radeon HD 7750 1gb and a 300 watt ATX Power Suppl.

I also have a monitor that I can use for this method. However I was thinking that instead of buying the external graphics card dock that may or may not work, I can buy a cheap intel mobo online and use an old case I have kicking about at home. I will then plug the psu and gpu into the mobo and put the mobo into a nice small form factor case. I will then use an HDMI cable to plug the graphics card machine box into my laptop and it should work.

Would this be a good solution? Or am I just dreaming? Here are my laptop specs by the way in case you need them: i3 3200U, 4gb ram, intel hd 4000 graphics, windows 8.

Many thanks in advance!!
 
Solution
it wouldn't work, the only way to connect a graphics card to a pc/laptop is by using pci express, hdmi is only used to connect a computer/set top box/console to a tv/monitor. Chances are that you will have to temper with your laptop inside.

I really don't know about external docks, i would just recommend buying a pc, but not a prebuilt. (maybe used components?)

If this was a viable solution, there would be a kit made by some company to easily make the required connections.

By the time you added the required components to actually power up the motherboard, you might as well just build a system for running games.
