Beware of Ahtec laptops

A year and a half ago I bought an Ahtec laptop from one of its Spanish distributors (Ampliware), the price was competitive enough and was one of the few places I knew that sold laptops without Windows installed so back then it seemed a good idea.

The computer worked fine for a year and a few months, but unfortunately after coming back from my trip to the States the laptop would not boot (yeah, two weeks away with no one using it and then it doesn't work :-S).

As the warranty in Spain is 2 years I decided to get it to the same shop that had sold it to me to ask for a free repair, but unfortunately Ampliware seems to be out of business (no shops and all the phones i find in the internet seem to be dead) so I went to a different distributor that agreed to send the laptop back to Ahtec (which seems to be based in Netherlands).

It took a while for them to answer and the answer was not satisfactory. They said that the GPU had died because of the heat because of the fan exhaust was full of dust and that the warranty did not cover that since it was not a manufacturing issue.

That's quite shocking to me, a laptop is basically a black box so I could never ever had opened it to clean it up (the screws had a "warranty void if removed" sticker) thus the only way I can think of that the GPU would not die would be:
a) Not use the laptop much so the fan would not carry that much dust to the fan exhaust and it would not get blocked
b) The laptop being manufactured better so that the fan exhaust doesn't get blocked by dust

As asking for a) is kind of a no go for a laptop ("Sir here you have the laptop, but do not use it much or it will break) so I'd go for b) the laptop was either manufactured or engineered incorrectly and in my opinion that means it should be covered by the warranty.

The problem is that the shop that sold it to me is gone so i can not ask/complain/sue them and that the manufacturer is not from Spain so fighting for my warranty to be honored will be too expensive.

So anyone wants to buy some laptop parts? 2GB PC3-8500 RAM stick? P8700 CPU? 320GB HD?
