Hi

Actually I posted something like that in the wrong section. I think it's more appropriate to post it in this section.

I will start off with what I had done for (modding)a few of the xbox 360.

That's awesome! Do you sell any of these custom xbox360 or provide service to customize it?

Yes, but only a few customization. I will sell it. I can too provide the same as the photo. But hardware prices depends on the items installed.

Great! I would like to know how much it will cost if I want to customize the xbox 360 with a display either on the casing itself or in a portable shape like the briefcase in the photos above. Does it have speakers too?

You got PM. Let me know about ur opinion and options

HOW DID U DO THIS.

soldering and some modification on the xbox motherboard. It's not as simple as it looks. A lot of troubleshooting and testing and soldering. And also getting everything cut and fitted and running all wires around.

How much estimation cost for DIY like this?

Rm1k plus (not including the console)
