yah sure... HP now offers extended warranty and many people are happy with the service they provide, its basically depends on kind of people you encounter at the service center.. heating is not the much of a problem , use a cooling pad or elevate it using some support for air flow... and whats gaming without the audio play with full volume ..

(btw i never heard any hdd noise problm in any topic, let the owners have their say.)
BTW in 500 gbp = rs 37500 u wont get a lappy powerful enough to fulfil ur gaming needs at that extent...even if u get from UK international warranty is again a problem..
