I'm sure some overheat, but we put a larger power supply in my wife's dell with one of the best cooling fans I've ever seen. the thing is huge, and kicks air out like mad. her system runs so cool, even when playing intense games it parly increases by more then 5 degrees.

Every manufacturer sucks, and every manufacturer puts out great machines.. varying from model to model.

I WOULD be careful though and check memery slots available.. many budget machines only have 2 slots,and that limits how much ram they can hold.

Way too many people take way too many things way too seriously.
