I would be very interested, because I would like to buy a notebook and would like to do so. If that works, could someone please also suggest a page on which you can buy housing?
It is possible but as already mentioned do not take a finished laptop, but a kind of laptop case and then you can let him assemble like a PC or self. However, it is more expensive and expensive. As you mentioned gaming I would advise against a laptop. I also wanted to be mobile but think it over again.
Did you use Google for times? Are some pages that offer that.
However, I guess from notebooks to gamble absolutely, as a PC is much cheaper and not so fast dies of heat death. So think in advance if you want to take the risk. If you have the opportunity to put down a PC, I would definitely prefer that.
As most people have already said: Prefer a stand PC, it is better suited and can be better ventilated and re-modified.
Otherwise, there are very good gaming laptops.
My favorites are from Alienware, because you can also choose for each model, what (default) hard drives, etc. Should be installed.

But that costs a lot. At these prices, you can just put together a top gaming PC.
